Hello one and all, Have a Glock 17 -- and needless to say it is one GREAT pistol ! ! -- but is shoots low when using 115 grain bullets, which is what I use most often for practice ammo. Shoots dead-on with 124 grain bullets (carry 124 grain Remington GS +P HP's in my 17, 19 and 26). So . . . I found a set of Low-Profile MMC adjustable sights for Glocks. Anyone have any experience with the MMC adjustable sights ? ? Thanks ! !
