Recoil Buffers have been a mainstay of serious 1911 shooters for many years. They are used and recommended by the best gunsmiths in the country. The repeated impact of the slide to the frame can result in cracking of the slide or frame. Use of a recoil buffer will prevent this from happening to you.
The recoil buffers will fit in all 1911 guns, which includes the government, commander, and officers models. One buffer will last between 500 and 1,500 rounds depending upon the gun and the load being shot.
