The Rock Island M1911 GI Standard is a high quality reproduction of the original USGI combat issue 1911 handgun. Experience modern quality with a classic aesthetic with this 45 ACP pistol. The slim wood grips offer a great feel in the hand and the all steel construction gives it a weight that is great for recoil absorption. The slide and frame are Parkerized for a deep black finish that contrasts with the light colored wood grip panels. The standard 5” barrel features a balanced weight to also help with recoil reduction and accuracy. Additionally, the trigger features the same crisp break you have come to expect from a quality 1911 pistol with a short reset/takeup and a combat ready 4-6 lb. pull weight. The fixed low profile sights and slim hammer round out that classic GI aesthetic making this Rock Island Armory 1911 GI pistol a great addition to your collection that you won’t be afraid to shoot.
