Gas-operation is a system of operation used to provide energy to operate locked breech, autoloading firearms. In gas-operation, a portion of high-pressure gas from the cartridge being fired is used to power a mechanism to dispose of the spent case and insert a new cartridge into the chamber .
The blowback principle may be considered a simplified form of gas operation, since the cartridge case behaves like a piston driven by the powder gases. [1] Other operating principles for self-loading firearms include delayed blowback, blow forward, gas operation, and recoil operation.
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.

Blowback firearms sometimes lack an extractor as they really aren't necessary for this method of operation. Delayed blowback This action is found where recoil is light enough that a fully locked breech is not necessary. Like simple blowback, it is case movement that opens the breech. This is a more robust version of simple blowback.
The blowback operation is a system in which semi-automatic and fully automatic firearms operate through the energy created by combustion in the chamber and bore acting directly on the bolt face through the cartridge. In blowback operation the bolt is not locked to the chamber, relying only on spring pressure and inertia from the weight of the ...
Firearms with a direct impingement design can, in principle, be constructed lighter than piston-operated designs. Because high-pressure gas acts directly upon the bolt and carrier in a direct impingement system, it does not need a separate gas cylinder, piston, and operating rod assembly of a conventional piston-operated system, only requiring a gas tube to channel gas from the barrel back ...
The Walther CCP is operated by a gas-delayed blowback system, using gas pressure from the ignited cartridge by directing it through a small port in the barrel in front of the chamber to slow down and delay the rearward motion of the slide. This design is nearly identical to the design of the Heckler & Koch P7. Walther calls this system Softcoil.
