Had one on a .22 Buckmark that let me shoot it like a rifle-nice squirrel gun. Have one on a FN Reflex-shoots very well. That said, I can still put bullet on steel faster with the irons on my EMP 9, my Sig .45 1911, and my Bond Bullpup than I can with the Dot equipped pistols. I’ve got 500 rounds + through the Reflex with the dot but I’m still slow than with irons-I “may” be a tad more accurate with the dot (or maybe I’m just shooting slower so that’s why. In any event I’m not yet carrying a dot equipped pistols for serious work
