In non-recoil-operated firearms, it is generally the entire firearm that recoils. However, in recoil-operated firearms, only a portion of the firearm recoils while inertia holds another portion motionless relative to a mass such as the ground, a ship's gun mount, or a human holding the firearm. The moving and the motionless masses are coupled ...
Firearms use triggers to initiate the firing of a cartridge seated within the gun barrel chamber.This is accomplished by actuating a striking device through a combination of mainspring (which stores elastic energy), a trap mechanism that can hold the spring under tension, an intermediate mechanism to transmit the kinetic energy from the spring releasing, and a firing pin to eventually strike ...
Gun control, or firearms regulation, is the set of laws or policies that regulate the manufacture, sale, transfer, possession, modification, or use of firearms by civilians. [ 1 ] [ 2 ] Most countries allow civilians to own firearms, but have strong firearms laws to prevent violence.
Also, if losing possession of the firearm is imminent, the operator can render the firearm useless by removing the magazine. [2] Firearms expert Massad Ayoob found instances where during a struggle, police officers carrying a pistol with a magazine disconnect were able to prevent being shot with their own guns by ejecting the magazine.

Blowback is a system of operation for self-loading firearms that obtains energy from the motion of the cartridge case as it is pushed to the rear by expanding gas created by the ignition of the propellant charge. [1] Several blowback systems exist within this broad principle of operation, each distinguished by the methods used to control bolt ...
Self-loading firearms are designed with varying rates of fire due to having different purposes. The speed with which a self-loading firearm can cycle through the functions of: Fire; Eject; Load; Cock; is referred to as its cyclic rate. In fully automatic firearms, the cyclic rate is tailored to the purpose the firearm is intended to serve.
A break action is a type of firearm where the barrel(s) are hinged and can be "broken open" to expose the breech. Multi-barrel break action firearms are usually subdivided into over-and-under or side-by-side configurations for two barrel configurations or "combination gun" when mixed rifle and shotgun barrels are used.
Locked breech is the design of a breech-reloading firearm's action. This is important in understanding how a self-reloading firearm works. In the simplest terms, the locked breech is one way to slow down the opening of the breech of a self-reloading firearm when fired. The source of power for the movement is recoil.
