most models have an additional grip safety that must be held in order for the pistol to fire, with the exception of the Combat Delta models that use the gun's usual grip safety. The pistols feature a very weak blowback, and the slide usually only moves a third of the distance that it would on a typical GBB or real firearm.

Refrigerant is sold in canisters similar to small propane canisters used in portable gas range. Propane based "Green" gas can be used, but could damage the replica due to higher pressure it exerts to mostly plastic parts used in gas blowback replicas, but many replicas have proven safe to use with propane or green gas.
