I bought a T/C .45 and it came with buck horn/post sights that I replaced with factory adjustable rear and globe front sights. The gun is shooting 3-4" high @75 yards with PRB and I cant adjust the rear sight down any more, it bottoms out. Front sight is .380 off the barrel and I havent found any Hawken style front sights any taller. I might be able to grind off some of the adjust screw threads enough to get on center. Anyone every run into this problem? And please dont tell me to put the buck horn sights back on. Thanks, Mike
