Walther P38

Firstly, The Walther P38 is a 9 mm semi-automatic pistol that was develop by Walther arms as the service pistol. Secondly, of the Wehrmacht at the beginning of World War II. Thirdly, It was intended to replace the costly Luger P08, the production of which was scheduled to end in 1942.

Firstly, The P38 was the first locked-breech pistol to use a double-action/single-action (DA/SA) trigger. Secondly,  (the earlier double-action PPK was an unlocked blowback design. Thirdly, But the more powerful 9x19mm Parabellum round used in the P38 mandated a locked breech design). The shooter could load a round into the chamber, use a de-cocking lever to safely lower the hammer without firing the round, and carry the weapon loaded with the hammer down.

P38 Pistol

A pull of the trigger, with the hammer down, fired the first shot and the operation of the pistol ejected the fired cartridge case, loaded a fresh round into the chamber and cocked the hammer for single-action operation for each subsequent shot, all features found in many modern day handguns. Besides a DA/SA trigger design similar to that of the earlier Walther PPKs the P38 featured a visible and tactile loaded chamber indicator in the form of a metal rod that protrudes out of the top rear end of the slide when a round is present in the chamber.^[2]
