Anyone using these sights on a carry gun? I rarely see any threads on Dawsons here, and that is surprising to me. I have installed their fiber optic front sights on a few 1911's and have been happy with them. Thinking getting a set of front and rear fiber optics for a just acquired Glock 23. I have a set of Ameriglos on a Glock 31 and am not impressed with them. Looking for opinions from anyone who has Dawsons. Thanks.
