Well made as all aimtech's are - Aimtech Scope Mount For Colt 1911, Colt Government 45 APM7

While I was still able to get the pin thru the mainspring housing and into the mount properly, there has to be a better way. I did put this on a Kimber Custom II, not sure if all 1911's have the same issue.
Pros: Perfect fitment
Cons: Pin/screw going thru the main spring housing, can't get it thru with out marring the threads.
