This version of the Beretta M9 model is all metal, full blowback, and a killer CO2 airsoft pistol. Fits in all standard Beretta 92/M9 holsters. Includes a metal under rail to attach lasers or lights. Another cool feature about this gun: it can switch to full-auto! There's a select-fire switch on its rear side that allows for full-auto firing. This gun is nuts!
