Pneumatic pistol

Pneumatic weapons such as the Pneumatic pistol are more commonly referred to as air guns such as air pistol or air rifle. Most Pneumatic weapons rely on "breaking" the barrel, a process which involves pulling down on the barrel so that it hinges near hand grip and which stretches a spring which can then be used to push air down the barrel when it is realigned once more. Most air pistols are single shot breech loaders by nature (somewhat like an old shotgun) although models which rely on compressed gasses contained in a canister such as the markers used in paintball matches.
