Mount according to directions. - Aimtech Scope Mount For Colt 1911, Colt Government 45 APM7

I purchased a 10mm 1911 for hunting and I wanted to put an optics on it and I found this while looking through optics world web page and it was just what I was looking for. I got it and it looked simple and I thought I could mount it just using the grip screws instead of using the special screw pins that replace two of the frame pins. Needless to say the 10mm has to much power for just the grip screws they kept coming loose and throwing off my scope, so use the supplied pins that come with it.
