Perfect match with burris fastfire iii and my glock 19 - Burris FastFire Reflex Red-Dot Sight Mounting Plates

This mount is used for mounting my new Burris Fastfire III red dot sight to my Glock 19. It does exactly what it supposes to do. It is an easy installation process, I don't need to read the instruction manual at all. The most difficult part is to remove the rear iron sight of the pistol and one extra step need to be take care of, the two mounting screws for dovetail need to be shorten for approx 1/32" otherwise it can't be tighten since they will hit against the base of the dove tail, in the worst case, it may strip the thread. I read other reviews before I bought this so I knew about this problem. This is not a new product so the manufacturer should address this problem long time ago. One star is removed because of this.
