This is a wonderful replica of the Classic Colt 1911 45 auto pistol. It is about as close as you can get to the real gun without actually owning the real Colt 45. The Cybergun Tanfoglio Witness 1911 is all metal with a realistic single action trigger, full blowback, a working grip safety and a full size drop out magazine that holds both the CO2 and teh 4.5mm Steel BB's.
