So I have at this point about 6 different guns with none having the same sight pictures... well other than the revolvers. I am looking to find a sight set that I can install on my Glock 17 and 19, and I am picking up a P220 tomorrow. So I am looking for sights that I can buy for those three as a start, but they also need a 1911 version. At this point all I can find are the Heine Straight 8s. Any others I should look at?
