obtained to provide a different pitch to suit the hand of an individual shooter.

The characteristics of the .25 Automatic Pistol cartridge have been given in Chapter 30. Following are the characteristics for the .32 Automatic Colt Pistol cartridge, known in Europe as the 7.65mm Browning: This cartridge shoots a lead bullet with a full metal jacket weighing about 74 grains at a muzzle velocity of approximately 965
The Mauser 7.65 mm (.32 ACP) Pocket Model feet per second. The striking energy at the muzzle is about 152 foot pounds. The bullet has a penetration in % inch board of soft pine of 3 boards at a distance of 15 feet from the muzzle.
These pistols are customarily of fine material, workmanship and construction. They are equipped with a thumb operated safety but do not have the automatic grip safety found in the Colt type. These are striker operated weapons. A spring housed within the striker pin is compressed when ready to fire. Upon release by the sear the spring drives the striker pin forward to fire the cartridge. When the striker is cocked, the head protrudes through a slot or hole in the rear of the slide. Thus, when this pin can be felt or seen, the striker is cocked.

The New Model (Neues Modell) 7.65 mm (.32 ACP) Pocket Pistol
Note, however, that this does not necessarily mean that there is a cartridge in the chamber, as this is a cocking indicator and not a cartridge indicator. This good feature also has certain drawbacks. If the pistol is dropped and hits on the striker-projection, it is possible at times for the striker to be jarred off the sear to fire the chamber-cartridge.
A magazine safety is also an integral feature of these arms. When the magazine is withdrawn, the weapon cannot be fired. This prevents danger from a loaded cartridge remaining in the chamber when the magazine has been withdrawn. An automatic interceptor functions when the slide recoils to break the connection between the trigger and the sear, thereby preventing the1 firing of more than one shot for each pull of the trigger. The thumb safety is of unusual design, and consists of two parts. A thumb lever on the left side of the grip behind the trigger is pushed down to positively prevent firing. This also locks the slide so that the breech cannot be opened. Pressing the spring-controlled button directly below the thumb lever releases the lever and sets the pistol ready for firing.
When the last cartridge has been fired, the slide is held open. Inserting a loaded magazine, then drawing back slightly on the slide will release it, and allow it to go forward under the pull of the recoil spring to chamber a cartridge and leave the weapon ready to resume firing. The substantial grip, good balance, absence of projecting parts and flat shape make this a good pocket pistol. This model belongs tc the blowback category listed by the Germans as "Mit Federverschluss" or "with spring lock."
Because of the comparatively low power of the cartridges employed, a secure breech locking system is not necessary. The weight of the moving parts and of the springs resisting the opening of the breech hold the breech closed long enough to permit the pressure to drop before opening appreciably.
The arm is loaded in standard fashion. A loaded box magazine is inserted in the grip from below and pushed in until the magazine catch locks and holds it securely. The slide in this arm is of unusual design and does not enclose the entire top of the barrel in common pocket automatic pistol fashion. However, it is machined at the rear to provide the customary gripping surfaces, and when this breechblock-slide is drawn back it cocks the striker and permits a cartridge to rise in the magazine. When the grip on the slide is released, the recoil spring housed below the barrel acts to draw the slide forward to chamber a cartridge and leave the weapon ready for firing.
The barrel design is unusual in that it carries the front sight at its forward end, while its underside is provided with projections to permit locking it firmly to the receiver as the rear projection is worked down into a slot in the receiver, and the recoil guide spring rod inserted from below the muzzle passes through a ring under the barrel in the front projection.
