The Walther P38 (originally written Walther P.38) is a 9 mm semi-automatic pistol that was developed by Carl Walther GmbH as the service pistol of the Wehrmacht at the beginning of World War II. It was intended to replace the comparatively complex and expensive to produce Luger P08. Moving the production lines to the easier mass producible P38 once World War II started took longer than expected, leading to the P08 remaining in production until September 1942, and pre-existing copies remained in service until the end of the war. As the Luger P08 was expensive to produce, Germany started to look for a replacement as early as 1927, settling on the Walther P38 in 1938, which offered similar performance to the Luger P08, but took almost half the time to produce. The first design was submitted to the German Army and featured a locked breech and a hidden hammer, but the Army requested that it should be redesigned with an external hammer. The P38 concept was accepted by the German military in 1938 but production of prototype ("Test") pistols did not begin until late 1939. Walther began manufacture at their plant in Zella-Mehlis and produced three series of "Test" pistols, designated by a "0" prefix to the serial number. The third series pistols satisfactorily solved the previous problems for the German Army and mass production began in mid-1940, using Walther's military production identification code "480". Several experimental versions were later created in .45 ACP, and .38 Super, but these were never mass-produced. In addition to the 9×19mm Parabellum version, some 7.65×21mm Parabellum and some .22 Long Rifle versions were also manufactured and sold. The P.38 was a cutting edge semi-automatic pistol design, which introduced technical features used today in current commercial and military semi-automatic pistols, including the Beretta 92FS and its M9 sub-variant. The P38 was the first locked-breech pistol to use a double-action/single-action (DA/SA) trigger (the earlier double-action PPK was an unlocked blowback design, but the more powerful 9×19mm Parabellum round used in the P38 mandated a locked breech design).

Service pistol

A service pistol, also known as a personal weapon or an ordnance weapon, is any handgun issued to regular military personnel or law enforcement officers. Typically, service pistols are revolvers or semi-automatic pistols issued to officers, non-commissioned officers, and rear-echelon support personnel for self-defense, though service pistols may also be issued to special forces as a backup for their primary weapons. Pistols are not typically issued to front-line infantry.

Handgun

A handgun is a firearm designed to be usable with only one hand. It is distinguished from a long gun (i.e. rifle, shotgun, submachine gun, or machine gun) which needs to be held by both hands and braced against the shoulder. The two most common types of handguns are revolvers and semi-automatic pistols, although other types such as derringers and machine pistols also see infrequent usage. Before commercial mass production, handguns were often considered a badge of office—comparable to a ceremonial sword—as they had limited utility and were more expensive than the long guns of the era.

Luger pistol

The Pistole Parabellum or Parabellum-Pistole (Pistol Parabellum), commonly known as just the Luger or Luger P08, is a toggle-locked recoil-operated semi-automatic pistol. The Luger was produced in several models and by several nations from 1898 to 1949. The design was first patented by Georg Luger. It was meant to be an improvement of the Borchardt C-93 pistol, and was initially produced as the Parabellum Automatic Pistol, Borchardt-Luger System by the German arms manufacturer Deutsche Waffen- und Munitionsfabriken (DWM).
