The sear spring also serves another function, powering the slide lock lever. Makarov pistol parts seldom break with normal usage, and are easily serviced using few tools. [16] The PM has a free-floating triangular firing pin, with no firing pin spring or firing pin block. This theoretically allows the possibility of accidental firing if the ...
The P-64 is a Polish semi-automatic pistol designed to fire the 9×18mm Makarov cartridge. The pistol was developed in the late 1950s at the Institute for Artillery Research (Polish: Zakład Broni Strzeleckiej Centralnego Badawczego Poligonu Artyleryjskiego, which later became the Military Institute of Armament Technology, Polish: Wojskowy Instytut Techniczny Uzbrojenia w Zielonce—WITU) by a ...
Mainsprings can come in many shapes, such as a cylindrical spring (Mosin-Nagant, TT-33, Colt M1911), plate spring (Nagant revolver model 1895, Makarov pistol) or spiral spring (Kalashnikov). On a number of automatic firearms, the recoil spring may also function as a mainspring (FN Browning M1900, Degtyaryov machine gun, and some submachine guns).

This lever transfers that energy to a spring-loaded weight located in the grip. The weight travels down, compressing its spring, then slams back up into the trigger bar, tripping the sear and firing the gun. Effectively, the rate reducer, which reduced the automatic rate of fire from 1,000 RPM to 750RPM, also acts as the auto-sear.
The human body has 78 organs and each one performs a variety of important functions. While it's possible to live without organs like the appendix , gallbladder, or spleen, several of our organs ...
