Walther PP vs. PPK vs. PPK/S: How to Tell Them Apart

Three pistols that look almost identical at arm's length, built for nearly a century in four countries. One of them exists only because of a 1968 US import law. Two measurements tell you which model you have, and the slide markings tell you where and roughly when it was made.

Why these pistols matter

Walther introduced the PP (Polizeipistole, "police pistol") in 1929 and the smaller PPK a year or two later. The PPK's name is usually read as Polizeipistole Kriminalmodell, a detective's model meant to be carried concealed, though some sources say the K stands for kurz, short. Both were among the first commercially successful double-action semi-automatic pistols: the first shot can be fired with a long trigger pull from a lowered hammer, and the slide-mounted safety also drops the hammer safely. That design influenced handgun makers for decades. The PPK is also the gun most people picture when they think of James Bond; see our Top 5 Firearms in James Bond for how it replaced the Beretta in Dr. No.

1. The model: barrel, grip, and magazine

• PP vs. PPK: the quickest tell is the back of the grip. On a PP you can see the steel backstrap of the frame between the two grip panels. On a PPK the grip is a single piece that wraps around the back. The PPK's slide and barrel are also visibly shorter.
• PPK vs. PPK/S: the slides look the same. Set the pistols side by side, or measure, and the PPK/S grip is taller, with room for one more round. Many PPK/S slides are marked "PPK/S"; trust the frame and magazine over a swapped slide.
• Calibers: most are .32 ACP (7.65mm) or .380 ACP (9mm Kurz). There are also .22 LR versions and a few rare .25 ACP PPs. The caliber is marked on the slide; check it before buying ammunition.

2. Why the PPK/S exists

The US Gun Control Act of 1968 set import standards for handguns, scored on points for size, weight, and features, and the small PPK no longer qualified for import. Walther's answer was to put the PPK's slide and barrel on the larger PP frame, which added enough size to pass. The result, the PPK/S, became the version most Americans bought for decades, and the "S" is a good sign that a pistol was made for the US market. The PPK itself came back to US buyers once it was made in the United States, where the import rules don't apply.

3. Reading the slide: who made it and when

The left side of the slide carries the maker's name and location. It is the fastest way to place a pistol in time:

• "Carl Walther Waffenfabrik Zella-Mehlis (Thür.)": made in Germany before the end of the Second World War. Wartime examples may carry military or police acceptance stamps, usually an eagle over a number or a letter. Late-war pistols often show rougher machining and finish.
• "Manurhin": the French firm Manurhin built PP-series pistols under license after the war, and some pistols sold as Walther-made in this period use Manurhin parts.
• "Carl Walther Waffenfabrik Ulm/Do.": made in West Germany after Walther re-established itself in Ulm.
• Interarms (Alexandria, Virginia): the long-time US importer and, from around 1980, the name on PPK and PPK/S pistols made in the United States under license.
• Smith & Wesson: built the PPK and PPK/S under license in the US from 2002 until the late 2010s.
• Walther Arms, Fort Smith, Arkansas: current US production.

Wartime acceptance stamps and party or police markings add a large premium, so they are also among the most faked markings in collecting. If a price depends on a stamp, get a second opinion from someone who handles these pistols regularly. Our war bring-back firearm guide covers the paperwork for a pistol that came home after 1945, and our Luger P08 guide covers the other German pistol that often came with it.

Value reference (2026 US market, approximate)

Values are for original, working pistols with matching numbers and the correct magazine. Refinished guns and swapped slides drop sharply. Scarce calibers and documented wartime acceptance sit at the top of each range.

So what do you have?

Check the back of the grip and the barrel length first: exposed backstrap and a longer barrel means PP; wraparound grip and short barrel means PPK; short barrel with a taller grip means PPK/S. Then read the left side of the slide for the maker and place, which dates the pistol to before 1945, post-war Europe, or US production. If there are wartime stamps, verify them before you value the pistol by them.
