I ordered and will recieve today my night sights for my USP Compact .45. My question is I have heard of people putting these in themselves, is that recommended by anyone here who had done it before, or should it go to a gunsmith? I dont want to damage either the sights coming out, or obviously the new ones. Yesterday, with considerable help from TooSixy, I swapped out the bobbed hammer, to a thumb hammer, and it is night and day. Now I love the gun even more. The reason I mention this is I can get my way through most gun issues if its not that hard. But the sights I have no idea of its level of difficulty. I dont have a gun smith very close too me(15 miles). Thanks.
