*We have found that some Sig Sauer 1911's with adjustable rear sights use a Kimber Adjustable style rear sight cut. Please measure the distance from the top of the front of the dovetail to the face of the sight cut in your slide. If this measures .43" you will need this (LPA) mount. If it measures .415" you will need the Kimber Adjustable.
Please See Our Common 1911 Dovetail Chart If You Are Not Sure Which Cut You Have.
 

This mount will NOT work with optics ready models
