G&G is well known for producing authentic replicas that function like, and are almost as durable as, their real steel counterparts. The GPM1911 Gas Blowback Pistol is no exception and is an exact 1:1 scale to the real M1911 model. While the real firearm's design hasn't changed significantly in the 100 years since it was invented, the G&G GPM has some innovative changes that make it the new standard for gas blowback pistols. Built with a full metal construction, this pistol is ready for any airsoft conditions and also has a realistic feel and weight which adds to the overall authenticity of the replica. The metal top slide slides back with every trigger pull, and leaves the user feeling satisfied with the sound and kick that is given. Many gas powered airsoft guns have problems achieving peak performance in cold weather, but this GPM1911 operates using a Whirl Cylinder Valve that reduces frost and provides high speed rotation from magazine to the chamber. A specially designed Internal Gas Filter was also used, which only allows gasified gas to be used as a propellant and restricts liquefied gas to inside the magazine. To ensure magazine safety and durability from being used under high pressure gas, a collapsible safety valve has been installed which becomes active once gas pressure has exceeded to avoid internal damage. The iron sights are perfect for zeroing your target quick and accurately, making this a perfect sidearm. Utilize the lower front rail system to attach a wide range of tactical accessories including lasers and flashlights. G&G used a specially designed ergonomic pistol grip for maximum comfort while providing increased stability and decreased player fatigue from elongated use. The fully adjustable hop-up makes it quick and easy to account and adjust for wind conditions and target range, or if you are changing the weight of the BBs you're using. The semi-auto 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.
