Thanks to the convenient power source of a CO2 cartridge makers are able to design and produce a replica 'automatic' pistol where the CO2 cart. is mounted in the magazine along with BB's. When the pistol is fired a unit in the slide (the top part of the pistol within which the barrel is supported at the front, is 'blown-back by a unit in the slide which uses CO2 . The slide cocks the hammer and as it runs forward it loads a BB into the barrel ready for the next shot.

A lot of these pistols are very accurate replicas, even down to field stripping. Great fun and highly recommended!
Thanks for the explanation
