The only pistols I shoot are glocks. Not because I like them but because I carry one for duty. I've found that my 17/22 framed guns shoot left and I have to bump the sights over. My larger frame 21 shoots center without adjusting the sights. Shooting left is one thing but shooting low left for right hand shooters is a pre ignition push. Have your budy load your magazine with ball and dummy. If your dipping the gun on the dummy rounds then you got to work on your trigger press. I dont notice it on dry fire, I'm solid, but ball and dummy I fall on my face.
