Our take: The all-new WG Full Metal Slide 1911 Special Combat .45 semi-automatic high-powered CO2 pistol is by far one of the BEST CO2 pistols we"ve ever shot. It"s a full size, metal slide, heavyweight replica, and one of the Best replica CO2 M1911 pistols on the market. Averaging a whopping 450 FPS with 0.20g seamless BBs at our chrono station, this CO2 pistol is recommended for TARGET-shooting use only, as it is extremely powerful. With a full metal slide and barrel, this CO2 semi-automatic airsoft pistol is built like a tank. It feels every bit as solid as it looks. A working hammer, movable full metal slide, and WG"s easy CO2 loading system, this full metal slide 1911 is a great alternative to gas-powered 1911s. With its unmistakably classic M1911 hand grip and a two-tone finish, it just also happens to be one of the most unique M1911 replicas you"ll find on the market today. An integrated lower front rail is also a great feature of this pistol, as you are free to add lasers/flashlights and/or laser & light combos easily to the front rail. * Features functional safety switch Specifications: Operation: CO2 repeater Firing Modes: Semi-automatic repeater Build: Full metal slide, Polymer Frame Muzzle Velocity: 420-460 FPS (w/ 0.20g BBs); recommended for target shooting only!
