This recoil buffer reduces metal to metal impact of slide to frame, reduces internal wear.

You will feel the difference the first time you cycle the slide.

You actually get ten (10) buffers in each package because the mfgr.

knows what a bear the M1911A1 .45 is, making the average life of these buffers about 800-1600 shots instead of the 3000-7000 life of rifle buffers.
