This is the last production automatic pistol designed by Mauser engineers before World War II halted their activities.

This arm uses the standard 32 Automatic Colt Pistol cartridge. The magazine holds 8 cartridges and another cartridge may be inserted in the chamber giving a capacity of 9.

The barrel is 3.37 inches long, the overall length is 6.5 inches, and the pistol weighs 20.6 ounces. The action is straight blowback, no lock being necessary in a weapon of this caliber and design.

This pistol incorporates a double action feature of general revolver type. Under this system, it is possible to carry the hammer down on a loaded chamber and to bring the pistol into rapid action by merely pulling straight back on the trigger. Through lever and spring arrangement, the hammer will be rotated to the rear and then slipped to hit the firing pin and discharge the cartridge in the chamber. The blowback or recoil will then force the slide back and cock the hammer for the succeeding shots in standard automatic pistol fashion. As in all automatic pistols, however, the firing chamber must be manually loaded for the first shot.

In all earlier forms of Mauser pocket pistols, whenever the chamber is loaded, the striker mechanism is at full cocf{. If an arm is carried this way, it is always potentially dangerous unless the thumb safety is kept applied. In periods of emergency, time may be lost in remembering to push the safety off. Another bad factor of this type of design is that if the weapon is carried ready for action, the striker spring is at full compression and may be weakened over a period of time.

With the double action feature, it is possible to carry the chamber loaded in complete safety with the assurance that the mainspring, not being under compression, will not be weakened. When it is desired to fire the pistol speedily, there is no necessity to think of safeties (though a thumb safety is provided to give double assurance to those desiring it). A pull on the trigger, as already stated, will fire the weapon without attention to any levers or buttons.

While the essential feature of this new Mauser pistol is the double action cocking system, it also represents a forward step in pistol development in the streamlining of design, in the shape and pitch

of the grip which permits more instinctive pointing, and in the simplified takedown system.

Parts of the Weapon

The principal paits of the arm are: The barrel, the slide whose rear section is the breechblock, the receiver which forms the grip and also houses the firing mechanism, the sights, the trigger mechanism and the safety. With the sole exception of the grips all parts are made of steel burnished for protection against rust. The grips are usually of plastic but may be of wood. (Note: Pistols made during the War were often poorly finished without burnishing).

The Barrel. The barrel forging is unusual. It is rifled with 6-grooves to the right. The rear chamber section is heavily reinforced and provided with an abutment against which the rear of the recoil spring, which is mounted concentrically around the barrel, is compressed. Two slanting teeth are provided on the underside of the chamber section of the barrel to lock securely into the receiver cuts prepared for them and provide a secure and positive mounting for the barrel.

The Slide and Breech Loc\ Mechanism. The slide incloses the barrel for its entire length. Its rear section serves as the breechblock, and it is suitably machined to travel back and forth in the receiver guides in a straight line. At its front end where it surrounds the barrel muzzle, it is machined to provide a seating for the forward end of the recoil spring.

In the breech section are housed the firing pin and its spring, the extractor and its spring, the safety, and a buffer pin each for the extractor and the safety.

When the pistol is assembled, a locking catch, spring controlled, which may be released by pressure on its projection in the forward end of the triggerguard, serves to keep the teeth on the underside of the barrel firmly locked to the receiver.

The firing pin and its concentrically mounted spring are of standard design; the spring serving to pull the firing pin back into the breechblock immediately after the firing pin (driven forward by the hammer) hits the primer of the cartridge in the chamber to discharge it. Thus as the action opens, the firing pin cannot be injured by the rearward pressure of the cartridge case being thrust back against the face of the breechblock, a thrust which is quite forceful in a blow-back pistol.
