For purposes of the General Law on Import and Export Tariffs, airsoft replicas as well as paintball guns and any other artifacts shooting projectiles of any kind through the use of compressed gasses (such as air, CO 2, propane, green gas, or red gas) that are not the result of the conflagration of gunpowder or similar substances, are classified ...
A light primer strike will result in a dead trigger and the gun will not cycle. This malfunction is not to be mistaken with a squib load which the gunpowder is ignited and the bullet fires, but is trapped in the barrel of a gun. A light primer strike will not have expanding gases as a squib load would produce as sign that there is one.
Red gas is usually avoided unless the airsoft gun has undergone modification, as its relatively high critical pressure can cause damage to the airsoft gun, such as breakage of the slide or bolt. CO 2, nitrogen, and high pressure air are less common because they need to be stored at higher pressures than "green gas" or HFC-134a.
These pistols and compact submachine guns are often more reliable than gas-powered replicas in cold weather. However, due to their lower voltage supplies and miniature gearboxes, they usually generate lower muzzle speeds (about 0.25 - .5J per BB, 25–50 m/s for 0.2g BB) and slightly slower rates of fire than replicas using a full-sized gearbox ...
An assortment of snap caps of varying calibers, from left: (1st row) .22 LR, 9mm (both), .45 ACP, (2nd row) 30-06 (both), (3rd row) 12 Ga. A snap cap is a firearm accessory device shaped like a standard cartridge/shotshell but contains no functional components, namely the primer, propellant and projectile (bullet or slug).
(I'd provide a link to the online version, but WSJ Online is a pay site.) (EDIT: the article said "9mm Glock" and was about Mark Barton. In my head "9mm Glock" translated to "Glock 17". May bad.) Common use would seem to apply to the the individual guns articles too. My position on the name of the gun is that it is not, in fact, "GLOCK".

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.
