Spring gun

Definition and stakes

Thomas W. Corbin,  The Romance of War Inventions

“ The gun is kept at the front part of the slide by means of a powerful spring, which is compressed when the gun is fired but which, as the force of the recoil is spent, pushes the gun back to its original position once more. The spring is often reinforced by a cylinder and a piston with compressed air or water behind it, acting after the manner of those door checks with which we are all familiar, its function being to steady the motion of the gun and to let it go gently back to its place without slamming, just as the door check prevents a door from slamming. ”

Henry Seton-Karr,  1911 Encyclopædia Britannica (1911)

“ A spring returns the extractor to its place when the empty cartridge cases have been ejected, and brings the barrel to an angle of about 45°, for convenience in loading. The soundness and rigidity of the weapon depend upon the efficiency of the connexion between the barrels and the standing breech, and a top snap bolt has proved the strongest and handiest with the pistol, as with the shot-gun. ”
