Factory replacement 17-round magazine for the 1911 Emperor Scorpion airgun. Features a locking notch so ammunition may be loaded more easily than traditional 1911 air pistol magazines. Now, not only does the air pistol weigh and feel like a standard 1911 pistol, but reloads like one as well. Along with the ammunition, the magazine also houses the CO2 cartridge. This allows for a similar experience as a standard 1911 reload. Compatible with SIG SAUER 1911 Emporer Scorpion and We The People air BB pistols. Includes allen wrench for CO2 replacement.
