I suggest that a qualified machinist/gunsmith familiar with Bomar installation be consulted. The slide of the M1911 will need to be milled/ drilled to fit the sight. This of course assumes that you do not intend to mount the sight high like the GI match guns. If that is your intant then installation is easier. BTW these sights should meet your match requirements.
