Walther Model 9 - Type I

The Walther PP (Polizeipistole, or police pistol) series pistols are blowback-operated semi-automatic pistols, developed by the German arms manufacturer Carl Walther GmbH Sportwaffen. 5 It features an exposed hammer, a traditional double-action trigger mechanism, 6 a single-column magazine, and a fixed barrel that also acts as the guide.

The Walther Model 9 vest pocket pistol was a very successful design that was manufactured for over two decades. During this time the designers and engineers at Walther were continually making changes to the pistol’s original design in order to improve the little gun’s function, market appeal, and ease of manufacture. These changes provide today’s collector with a rich variety of collecting options. Each type and sub-type of Model 9 has a separate and distinct appeal. This article provides a general outline of the variations, followed by a list that details the distinct Types and the numerous sub-variations of the Walther Model 9.
Model 9 Walther Types are based upon significant design changes that were made to the pistol at two points during the 20+ years of production. Around 1924 and again in 1934 (or possibly 1935) the designers at Walther made significant alterations to the fabrication and mechanical function of the pistol. These changes establish three distinct Types of the Model 9. Also during the production life of the Model 9 there were a number of smaller changes which improved the pistol slightly from a manufacturing or aesthetic standpoint but did so without significant internal design changes. These smaller variations are noted but individually do not constitute distinctly separate Types.
Total Model 9 production is estimated at around 250,000. Model 9 production volume was greatest in the early 1920s when the pistol was first introduced. During the first four years of production, from 1921 through around 1924, approximately 127,000 Type I Model 9’s were made. Then Walther made some significant changes to the pistol resulting in the Type II. Annual production volume fell off significantly and for the next 10 years, until around 1934, total production of Type II Model 9’s was approximately 108,000. In 1934 or 1935 Walther again changed the design significantly, resulting in the Type III. Model 9 production appears to have picked up slightly in 1938, before World War II broke out in September 1939. During the rest of the war years of 1940 through 1945 Model 9 production was very limited. Total production of Type III Model 9’s from 1934 until the Walther factory was shut down in May of 1945 is approximately 15,000, the majority of which were made prior to 1940.

Characteristics of the original design which describe Type I pistols and which changed over time:

  • Walther Model 9 - Type I

    The recoil spring has a pointed metal pin mounted at the front which fits into a corresponding indentation in the front cross bar of the slide.
  • The slot in the underside of the slide on the right side extends only ¾ of the way towards the rear of the slide.
  • The 3-digit serial number on the slide is stamped on the underside of the slide behind the ejector slot.
  • Grip retention is by blue enamel disks with brass. The left disk is attached with a screw from inside the magazine well. The right disk is attached to a threaded nut inside the frame using a small spanner wrench. The face of the left disk is marked with the “CW” monogram in an oval. The face of the right disk is marked with “6 .35”in an oval and has small holes for the spanner. Both grips are plain checkered black plastic panels with ribbed backs.
  • The Serial Number is stamped horizontally on the right rear of frame.
  • Crown over N proof marks are stamped sideways on the right side above trigger on the frame and directly above on slide.
    There is no magazine safety.
  • The “cup” that retains the striker spring on the slide retention bolt is about 2mm deep and the edge of the “cup” is even with the front of the slide retention bolt.

Note that the complete transition from Type I to Type II took place over a range of several thousand pieces, and aspects of both Type I and Type II can be found in this serial number range.
Minor Changes made during Type I production:
  • The extractor slot in the chamber of the barrel is not open, but has a thin sheet of metal which covers the extractor where it protrudes into the rear of the chamber on SN 410000 to approx 425xxx, after which the remaining metal of the extractor slot is milled away leaving the extractor exposed.
  • The sight groove is narrow (about 1.5mm) on SN 410000 to approx 503xxx, then the sight groove is widened (about 3mm).
  • The trigger spring is a coil spring on SN 410000 to approximately 525xxx, after which a flat trigger spring is used.
Type II
Virago 500 manual. Serial Number range: approximately 537xxx (1924) to SN 640xxx (1934).
Approximate Production: 103,000 +/-
Major Changes from Type I:

  • Walther Model 9 - Type II

    The pointed metal pin is no longer present on the end of the recoil spring. There is a tab milled directly into the cross bar at the front of the slide into which the front of the recoil spring is fitted.
  • The slot on the underside of the slide on the right side is cut almost the full length of the slide.
  • The last three digits of the serial number are stamped on the front of slide atop the cross bar.
  • Grip retention is by small exterior screws and decorative steel washers attached to threaded bushings that are pressed into the frame.
Minor Changes during Type II production:

Walther P22 Serial Number Dates

  • The rear of the firing pin is lengthened by approx 1.5 mm beginning around SN 540xxx. This makes it easier to “feel” when the pistol is cocked.
  • The serial number on the frame is stamped horizontally on right rear of frame up to approx SN 605xxx after which it is stamped on the left of frame downwards vertically behind the trigger through approximately SN 634xxx then on left of frame upwards vertically behind trigger.
  • Standard plain checkered black grip panels transition into checkered black grip panels with a large WALTHER logo on each side. Note: from approx SN 545xxx to 558xxx black grips with a plain right panel and a small WALTHER logo on the left panel are seen intermittently. All grip panels have ribbed backs.

Walther Model 9b

Model 9b
During the Type II production period Walther offered an upgrade to the standard Model 9 pistol that was designated the Model 9b. The 9b had an upgraded finish that reverted to the more decorative Type I style enamel grip retention disks, and in most cases the slide had acid etched engraving. The enamel retention disks are usually blue, but some are white . These handsome pistols were sold for a modest up-charge. Other than the grip retention disks the Model 9b was mechanically the same as the Model 9 Type II. The Model 9b should not be confused with special order Model 9’s which had high grade engraving and/or special plating and/or custom grips which are discussed below.
Type III
Serial Number range: approximately 641xxx to approximately 652xxx (1938) and then 190000N through 198xxxN (1940?).
Approximate Production: 19,000 +/-
Vim mac. Major Changes from Type II:

  • Walther Model 9 - Type III

    Magazine safety parts are added on right side of the frame behind the transfer bar. The grip frame is milled out to take the safety lever and a locking slot is milled into the transfer bar.
  • The “cup” that retains the striker spring on slide retention bolt is milled to be shallow (about 1mm) at the top edge of the “cup”. The front edge is at an angle to the front of the slide retention bolt.
  • Black checkered plastic grip panels with large Walther Logo on each grip have solid backs standard on all Type III.
Minor Changes during Type III production:
  • The grip retention by exterior screw and washer into threaded bushings pressed into frame are seen through SN approx 196xxxN then a new style of blue enamel retention disks attached through the magazine well is used.
  • Crown over N proof marks are found on the right side of the frame above the trigger and directly above on the slide until approximately SN 196xxxN, after which Eagle over N proof marks are stamped in the same locations.
There are examples of some very late production Model 9’s in which parts from all eras of production are assembled into complete pistols. These pistols appear to show that the Walther factory was using up all existing parts at the end of Model 9 production. It is not known exactly when Walther produced the last Model 9. It may have been as early as 1940, or possibly as late as 1945. Exact Model 9 production numbers and dates are no longer available. However, based upon the study of surviving examples it is possible to establish reasonable estimates of production quantities and dates.

Walther Model 9 High Grade

High Grade Model 9 Pistols
Throughout the entire production run Standard Model 9’s were available in either a high polish blue finish or with nickel plating. On a special order basis Walther offered high grade guns with custom finish options. In addition to the blue and nickel finish, gold and silver plating were offered. Walther’s famous high quality engraving service was also available. In addition, grips made of wood, ivory, or mother of pearl were options. Mechanically these beautiful Model 9’s were the same as the standard production type being made at the same time. High grade Model 9’s are seen in all types and variations.
Model 9 pistols with Import Markings
The Walther Firm was very active in marketing its fine products throughout the world in the period between WWI and WWII. On occasion Model 9 pistols will be found with various import markings required by different countries or added by retail outlets. These markings are found on all three Types of Model 9. Examples of these marks are tiny “MADE IN GERMANY” stamps indicating guns which were exported to the U.S.A., “VP over N” stamps with a serial number and a date stamped on pistols imported into Austria, a Rearing Lion with a serial number and a date stamped upon pistols imported into Czechoslovakia, and names and addresses of stores from San Francisco to Nairobi etched into the slide. Examples of exported Model 9 pistols are seen from the earliest 1921 production all the way until 1940. These markings add an interesting bit of personality to the guns that have them. The vast majority of Model 9 pistols seen in America do not have any import marks which implies that they were probably brought home from Europe by returning G.I.s who picked them up while serving during WWII.

Walther Model 9 Magazines

As with the Model 9 pistol, the magazines for these tiny guns evolved over time. The following outlines the various details of these magazines.
Walther Model 9 magazines have a six round capacity. They measure about 57mm long. Each magazine has 5 viewing holes in each side.

Three Magazine Bases

Model 9 Walther magazines are of an uncommon design in that they do not have the traditional extension on the baseplate for seating the magazine against the frame and for aiding in removal of the magazine. Instead Model 9s have a protrusion in the right side which seats against a stop milled in the side of the magazine well. All Walther-produced Model 9 magazines have a hole in the lower left side which allowed the stamping of the protrusion on the right side through the magazine. At the bottom of the magazine face there is a narrow “fingernail” groove for aiding in extraction of the magazine from the pistol.
As with the Model 9 pistol, magazines are found in a variety of finishes. Blued, nickel, gold, gold wash. In most cases, but not all, the finish on the magazine matches the finish on the pistol. There are instances where blued magazines were issued with nickel guns, and nickel magazines were issued with blued guns.
There are three variations of the base on Walther Model 9 magazines. The three variations are: Plain, flat bottom; plain, rounded bottom; and Walther logo marked bottom.
The earliest Model 9s have plain, unmarked flat bottoms. These early plain, flat bottom magazines are typically observed with Type I Model 9s from the beginning serial number of 410000 up through around 436XXX. Plain, flat bottom magazines do show up occasionally in later production pistols with high grade and/or engraved finishes. Flat bottom magazines are found in all finishes.
There is a short span of Type I pistols from Serial Number 438XXX through around 446XXX where Model 9 magazines with a plain, unmarked, and slightly rounded bottom are seen. All of these odd magazines are nickel finish. They are found with blued pistols as well as nickel finished pistols. Photo booth effects free. These magazines cease to be seen with any later production pistols.
The third and by far the most common Model 9 magazine bottom is stamped with the WALTHER banner logo. These magazines begin to show up on Type I pistols around serial number 438XXX and are seen throughout the balance Type I, Type II and Type III Model 9 production. WALTHER logo marked magazines are seen in all types of finish.

There are also three variations of follower used in Model 9 magazines. The three types of Model 9 magazine follower are: Swaged, rounded followers which appear identical to followers used with the Model 8. Flat stamped followers with an exposed front that does not cover the front of the magazine spring. The third type of follower is stamped with a front that bends over the front of the magazine spring.
Swaged followers are seen on magazines with flat bottoms and with WALTHER logo bottoms. Swaged followers are more common in earlier pistols.
The second type of follower that is flat, stamped steel and does not cover the magazine spring is the most common and is seen on magazines with all three types of bottom. All of the rounded bottom nickel finish magazines observed have this second type of follower. This type of follower is far less common on very late production pistols.
The third type of follower that is flat, stamped steel with the front that covers the magazine spring is generally seen on magazines issued with late production Model 9 pistols. This type of follower is seen with almost all Type III Model 9 pistols.

My dear vintage pistol collector friends,
I am posting this information for John Pearson (longtime Walther and vintage WW II era pistol collector). He no longer is a member of NAPCA and is not on the internet so I told him I would be happy to post this great information for him. In the course of the last number of months I have been visiting and corresponding with Mr. Pearson regarding Walther RSHA SS PP and PPK pistols. With his help (he is the author of the groundbreaking series of articles in “Auto Mag” regarding Walther RSHA SS PP and PPK pistols) I am trying to refine and define the various variations of these interesting pistols and their respective variation characteristics. In the course of those conversations and exchanges many items related to Walther PP and PPK Wartime (WWII era) production procedures and expediencies arose so John decided to produce an article for the vintage collecting community, especially those interested in wartime Walther PP and PPK production relative to serial number sequencing and production priorities as it relates to these pistols. It is an interesting and informative and somewhat complicated article (based on forty years of collecting data by Mr. Pearson) and requires careful consideration and pondering to really get what is happening. John has a mathematical background which is obviously a nice resource and skill when it comes to a subject of progressive divergent serial numbers in two different ranges of serial numbers (PP and PPK) and how Walther handled and did this as I said both from a production standpoint and priority standpoint. Anyway, I hope you enjoy this article and find it useful in understanding rather complicated production issues (at least to my simple mind this tends to be complicated to understand). John's sole purpose in producing this article is to further enlighten vintage pistol collectors and try to advance our understanding of some of these production issues and production changes that occurred during and before WWII. This article is or was produced only by Mr. Pearson (he is the sole author) and I DID NOT contribute or do anything for him in that regard--I am ONLY facilitating its introduction to a group of what I think are interested vintage pistol collectors. I believe, thanks to Mr. Pearson, the world of Walther pistol production and vintage Walther pistol collecting (PP and PPK) is perhaps a little less mysterious and perhaps we are a little more enlightened as a result. He has included his telephone number if you want to visit with him or have input or a difference of opinion he would be happy to hear from you.
Happy Holidays my collecting friends, Lloyd in Vegas
WALTHER MODEL PP & PPK PRODUCTION INFORMATION
My name is John Pearson and I have collected German semi-automatic pistols for almost 40 years, with one of my areas of special interest being Walther Model PP and PPK pistols. I have studied the numerous variations of these guns and also analyzed large amounts of serial number data on them. From that research I have discovered some interesting information about the production of these guns, which I am summarizing in this write-up. Hopefully this will clear up some mis-information about these very collectable Walther pistols.
The Walther Company introduced the Model PP (Police Pistol) in 1929, and serial numbers started at 750001. This would become the world’s most successful double action semi-automatic pistol, which at first was available only in caliber 7,65 m/m Browning (what we call the .32 automatic). After the Model PP was in production and showing success, Walther introduced a smaller variation called the PPK (Police Pistol Kriminal) that was presented in Germany as the Detective model. The PPK uses a shorter barrel, slide and magazine, had a one piece plastic wrap-around grip, and was designed for easier concealment. The PPK pistol was introduced into production in 1931/32, apparently starting with serial numbers around 757800. At first these pistols were also marked PP on the slide, but in the 7579xx serial block they began to be marked on the slide with the new designation of PPK. From this point in time both PP and PPK pistols were being assigned serial numbers intermixed in the same range up until almost number 999999, and it is generally not possible to tell by the serial number if a pistol is a PP or PPK Model.
At this point in the discussion let me make the following observation about serial number assignments in the Walther Factory. As orders came into the factory they were assigned serial numbers, starting with the next one available in sequential order. So for example if serial number 795123 was the last number assigned, and an order for 3 PPK pistols was received, they would be assigned serial numbers 795124, 125 and 126. But, Walther did not build the guns in a strict serial number sequence; they built guns in a priority sequence. Thus PPK 795124 might not be built until after a large batch of PP pistols were built in the 801xxx serial block. So when people ask, when a specific pistol was produced, it is frankly not possible to identify the manufacturing sequence or a production date for a specific pistol. We know, for example, that all serial numbers from 820xxx to 844xxx are PPK pistols with the RZM marked slide, but no one can say if a PPK in this range was produced before or after PP number 870xxx.
Sometime in 1938 Walther realized that they were going to have a problem with serial numbers, for their model 8 pistol (a smaller size 6,35 m/m semi-auto pocket pistol that had gone into production in around 1920) was now approaching serial number 750000 (the start of the PP pistol numbers). Keep in mind that Walther had never intentionally produced two guns with the same serial number, and now they needed to create a new serial number range for the Model 8. Their solution was to introduce an alpha suffix to be added to all of their different pistol model serial numbers. They chose the alpha suffix based upon the model of the pistol. Thus for the model 8 it became an A (acht or eight in German), for their Model 9 it became an N (neun for nine in German), and for their Olympia pistols they used the letter O. For the Model PP the suffix became a P, and for the Model PPK the suffix became a K. This change was made for all pistol production in the factory, but contrary to what many collectors believe, it had nothing to do with the fact that PP serial numbers had reached the 1 million range (1000000). To prove this I am listing a number of PP serial numbers which are just below the million range and that include the P suffix. You will note that some of these numbers are in the 99xxx serial block, and one does not include the P suffix, which demonstrates that this change was introduced with some confusion.
The serial numbers I have collected for these first P Suffix PP pistols are as follows:
997951P
997963P
998063P
998957
98977P
99013P
99025P
99210P
99239P
99428P
99453P
99705P
99930P
Note that 999530 is a PPK and does not have a K suffix at this point, proving that it had already been produced before the P and K suffix concept was implemented within Walther. Based upon these serial numbers, it is my assumption that PP number 998957 was also produced before the introduction of the suffix feature. Now notice that the first three numbers listed are in the nine hundred and ninety thousand range, and then the numbers with a P suffix revert to the range of ninety-nine thousand, because the high order 9 digit has been dropped from the serial number. This was done because of a recognized problem with PPK pistols which were already in the million serial block. I will explain this in the next paragraph, as we discuss the introduction of the K suffix on the PPKs.
From this serial number data it is apparent that the P suffix was introduced before the Model PP pistols had reached the million serial block, but at that same time the PPK pistols were already being numbered in the million serial number block. Remember that I said serial numbers were assigned well in advance of when the gun was actually produced, and when the assigned serial numbers for PP and PPK had reached into the million range no change had been made. For the PPK pistols, they had already been produced into the 10067xx serial range before this suffix change took place. It turns out that by this particular point in time apparently tens of thousands of orders had already been received at Walther for Model PP pistols, and numbers for these future PP pistols had been pre-assigned up to around 1072xxx. Thus when the PPK pistols were scheduled to start using the K suffix, the next pre-assigned number was around 10728xx. When a K was added to this number it became too large to fit on the frame, so what Walther did was to modify this number by dropping the high order 0 (zero) to become number 1728xx, and then the K was added. One such gun reported is number 172837K, which is apparently one of the very first PPK pistols with the K suffix added. PPK serials continued from that point with an added K Suffix, with the original assigned number being modified by shortening the number to the one hundred thousand range, rather than any more million range numbers. Of course newly assigned numbers from that point would no longer be in the million serial range.
For the Model PP pistols there had also been a large number of million range numbers already pre-assigned for their production. But since the change over to the P suffix took place just before the million serial was reached for PP pistols, Walther did not produce any PP pistols with a million range number. Like with the PPK numbers, for PP pistols they shortened the pre-assigned million range numbers to a number in the one hundred thousand range. For example, the originally assigned PP number of 1000249 became 100249P, etc. It is for this reason that many collectors believed that the suffix was introduced at the million serial number, but I have shown that it was not. I hope that all of this is understandable as you reread the above narrative. Also, keep in mind it was never the intention for Walther to produce two guns with the same serial number, so there will only be one pistol serial number with either a P or a K suffix. There might be a few mistakes made by the factory which resulted in applying duplicate numbers to guns, but most “duplicate” serial numbers are actually reporting errors by collectors or those who do the data base processing.
The next important thing to understand is that PP number 997951P was produced at essentially the same time as PPK number 172837K, thus there is a “spread” of some 75,000 serial numbers difference between the PP being produced and the PPK being produced at this point in time. Remember this point, for that means that PP number 172500P was made many months after PPK number 172837K. Over time this “spread” will even increase more. Also, once the War had started Walther received far more orders for PP pistols than PPK pistols. Based on my research, during the War the Walther Factory produced a percentage mix of roughly 60% PP pistols and 40% PPK pistols.
Up until this point we have been talking about commercial quality Model PP and PPK pistols. It was probably in 1941 that Walther made a number of changes to PP and PPK pistols. These changes were not all made at once, and included the following in no particular order: The long overhang tang frame was introduced, the chamber was left blue rather than bright, the safety lever and extractor were standard blue rather than the fire blue finish, and the full serial number now became standard on the right side of the slide. Up until this point in production, for most guns only the last three digits of the frame serial number of the pistol were scratched on the inside of the slide. These changes first appeared for PPK pistols in the 33x,xxxK serial range, and for the PP pistols in the 22x,xxxP serial range. If we assume that these changes took place for both the PP and PPK at the same time, this reveals that the “spread” I had previously discussed had now increased to 110,000 serial numbers.
The next big change was to eliminate the high polished finish on the guns and to instead use what we collectors have come to call a military or milled finish. The blue applied was probably the same, but since the metal parts were no longer given a high polish finish first, the milled finish blue looks quite different. For the PPK pistols this change was in effect by the 355xxxK range, and for the PP pistols this change was in effect by the 235xxxP range. It must be noted that there is a great deal of overlap with this changeover to the milled finish, and guns covering a range of thousands of numbers will be intermixed with both high polish and milled finish examples. This can again be explained by the fact that guns were being produced in priority sequence and thus serial numbered “out of order”.
Probably not too long after the introduction of the milled finish, certainly by 1943, production of the Model PPK began to noticeably slow down. For example, let us look at police marked guns, which changed over to the Eagle F (EF) marking late in the War. The first Police EF Model PP guns are found in the range of 354xxxP, and for the PPK they are first found in the range 423xxxK. Notice that this is only a “spread” of some 70,000 serial numbers, showing that PPK production by that point had slowed way down. We know that production of the PPK Model did not continue until the end of the War because there are no PPK pistols with the Walther “ac” code applied to the slide instead of the full legend markings. For the PP pistols we first see the “ac” slide marking by serial range 365xxxP. I do not know the exact date of the introduction of the “ac” slide marking, but it is assumed to have been by January 1945. The question has often been asked, when did PPK production essentially end, and I can not give any precise answer to that question. But it is very likely that PPK production ended in 1944, with the last few thousand PPK pistols produced using left over parts, such as aluminum frames which had been produced years earlier and then apparently put into storage. This is known because none of these late War alloy frames have the long overhang tang feature. We know that PP production had essentially ended by serial 397000P, which is assumed to have been when the War ended. The highest serial numbers for the PPK models are found in the range 431xxxK (the highest I have recorded is number 431097K), revealing a “spread” of only 34,000.
The question has also been asked whether Walther produced guns and serial numbered them, but did not proof them and apply the final finish until later. It is true that Walther did do some of their factory engraving on guns and then put them into storage without ever completing them, but I have seen no evidence that this “storage” concept was ever done for standard production guns. We do find guns out of sequence, as for example with Eagle N proofed guns appearing before some higher numbered Crown N guns. But I attribute this to their priority production concept, where serial numbers were assigned to guns and then the actual production of those guns was delayed until later on, after the Eagle N proof mark had begun being used (early in 1940 - some experts say January 1940 and others say April 1940). I do not believe that any of these “out of sequence” guns were completed and put on the shelf to later get the Eagle N proof. It is my belief that Walther produced a gun with the serial number that had originally been assigned to it, and this is how “out of sequence” guns exist. All of this information means that during a given day on the Walther assembly line there could be Walther PP pistols that were 10,000 serial numbers apart, and that at the same time there could be a PPK pistol being manufactured that is 110,000 numbers higher. I know that this sounds crazy, but that is what the data proves was actually happening.
I hope all of this will be informative and useful to Walther collectors. The information that I have presented in this article was formed over many years of research and is based upon lots of real world data. I do not claim to be perfect but I believe that the information that I have presented here is quite accurate.
