Colt is well known for producing authentic replicas that function like, and are almost as durable as, their real steel counterparts. Their version of the 1911 Pistol is no exception and is an exact 1:1 scale to the real M1911 model. Built with a durable polymer slide and frame, this pistol is ready for all airsoft conditions. This 1911 pistol utilizes Co2 as the propellant, and the 12g cartridge is housed in the magazine. Authentic Colt trademarks are stamped onto the slide, so you know you are walking away with a quality product. Specially designed textured ergonomic polymer pistol grips were used as opposed to the classic wood, to create a more lightweight and durable platform. The grip provides a better suited non-slip surface in all weather conditions. The efficient non-blowback design gives players more bang for their buck by allowing more shots to be fired from the same 12g Co2 cartridge. Under the front of the pistol is a 20mm accessory rail for the use of an additional tactical accessory such as a flashlight or laser sight. The dimensions, slide lock, grip safety and thumb safety are all fully functional which adds to the overall authenticity of this replica. Internally, the high quality parts are made to last and withstand the constant pressure from the Co2. The semi-automatic design allows you to fire as fast as you can pull the trigger, with no delay or having to manually cock back the hammer between each shot. This is a great pistol for those looking for a reliable versatile sidearm that packs a serious punch.
