W.c multi-comp bushing (needed fitting "ria m1911a1 fs") - Wilson Combat Full Size Multi-Comp Bushing Compensator

I was able to fit the comp onto my RIA M1911A1 Fs when sanding down the bushing lock. The comp is currently still on the pistol after 50 rounds fired (Current count), and no failure have occurred. For recommendation: Using RIA M1911A1 Fs 45.ACP Standard model; you'll need to sand-down the bushing port for the comp until assemble/ removal is smooth and easy to do. Also removal of the comp with a full size guide rode; unlock the bushing as if your completely removing the bushing and use the guide spring and plug to aid in removal as the comp makes it difficult to remove the spring individually.
