Semi-automatic pistols

Semi-automatic pistols, a handgun that uses either recoil or blowback after each shot to fire the empty bullet, reload and cock the piece. The semiautomatic pistol dates from the very late 19th century, when ammunition advances made it possible to feed or cycle cartridges and bullets smoothly via an autoloading system.Buy Handguns Online, Buy Firearms Online

Semi-Automatic Pistols Functions

There are a few fully automatic weapons that are capable of cycling and discharging a magazine of cartridges with a single trigger grip. Though sometimes referred to as “automatic,” with each pull of the trigger, the common semiautomatic pistol fires only one shot. Semiautomatic handguns are almost never powered by combustion gases, unlike semiautomatic rifles and shotguns. Rather the blowback mode of action is most frequently used in which the breechblock or bolt is locked in the firing spot, but is free to be propelled backward by the same energy burst that propels the bullet forward. In a spring, which in turn projects the bolt assembly forward and injects a new cartridge into the chamber, the rear thrust ejects the spent cartridge from the chamber, thus storing energy.

In the recoil method of action, at the moment of fire, the breechblock is fixed to the barrel. Thus the breechblock travels with it as the recoil of the gun pushes the barrel rearward.

The breechblock is unlocked from the barrel and starts to travel backward while the barrel ceases its motion as soon as the pressure of gases in the barrel has decreased to a secure amount. The rearward motion ejects the spent cartridge and loads a spring that moves the assembly of the breechblock forward again, loading, cocking and locking the piece again to fire.


Semiautomatic pistols are respected because in their magazines they can carry more ammunition than revolvers can in their cylinders and because of their superior fire rapidity. However, their precision is considerably less than that of revolvers in trained hands, except for target weapons. Often, it is not possible to say at a glance if as is possible with a revolver, a semiautomatic pistol is primed. In sizes usually ranging from .22 to .45 calibre and their metric counterparts, semi-automatic weapons are chambered.
