Detonics.45 GBB Pistol User Manual Detonics are an American-based company noted for their compact 1911 design pistols. Tokyo Marui's latest blowback pistol gives a nod of appreciation to their work, with this nice replica of the Detonics .45 compact pistol. With the all new stainless paint finishing, it enhanced the overall appearance of the gun, making it look much more like metal. The controls remain the same as a standard M1911, except with a smaller frame, shorter barrel and shorter sight radius. If you are into a concealable 1911, this is the one for you with the reliable Marui adjustable hop up system. Magazine holds 18 rounds of BBs This product is only compatible with gas designed specifically for Airsoft guns. Do not use lighter fluid or butane gas, as that will cause permanent damage.
