I've been doing some minor work on a new friend's Colt Government and we've had good success so far with the trigger. The problem I've ran into now is that we replaced the original spur hammer with a round combat hammer and the rear Bomar sight that someone installed on this gun overhangs the rear of the slide to a point where one does not have access to the round hammer at all. My friend wants to replace this rear target sight with something more traditional and would prefer a combat type sight. The dovetail cut that was made for this Bomar is huge. I measured the bottom of the dovetail and I came up with roughly .540". Is there any drop-in sight that could be used as a replacement to this big Bomar or is this something that is gonna require welding and recutting? Your thoughts are appreciated.
