In firearms, a blowback system is generally defined as an operating system in which energy to operate the firearm's various mechanisms, and automate the loading of another cartridge, is derived from the inertia of the spent cartridge case being pushed out the rear of the chamber by rapidly expanding gases produced by a burning propellant, typically gunpowder.

According to Newtonian mechanics, if the gun and shooter are at rest initially, the force on the bullet will be equal to that on the gun-shooter. This is due to Newton's third law of motion (For every action, there is an equal and opposite reaction). Consider a system where the gun and shooter have a combined mass m g and the bullet has a mass m b.

The pistol functions via the blowback principle - gas pressure from burning powder simultaneously forces the cartridge case and slide backward and forces the bullet forward in the barrel. After it reaches the end of its rearward travel, the recoil spring returns the slide to its forward position, stripping and chambering a new round from the ...
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 ...
The congressmen cited the troubling case of Bradley Wendt — a former police chief for Adair, Iowa, who was convicted earlier this year on federal charges related to obtaining military-grade ...
Blow forward (left) vs. blowback (right) operation. The Mannlicher M1894 pistol, the first blow-forward firearm.. Blow forward is a firearm action where the propellant gas pressure and the friction of the bullet traveling down the bore drag the whole gun barrel forward to facilitate the opening of the breech.
