I've got Novak's extreme adjustable mounted to my Glock. No offense to Novaks - they make superb sights, but my AA conversion has Dawson precision adjustables and by comparison, I would have never bothered with the Novak's on the Glock - the Dawsons are absolutely superb. Of course these are adjustable sights I am speaking of. Fixed sights are for defense shooters - I like to get more precision out of a pistol than that. Different rounds have different p.o.i., therefore the sights will need adjustment when you change loads to keep accuracy correct.
