I recently bought an S&W SD9 - I have put just under 300 rounds thru it and I am consistently shooting down and left. I’m off about 3” when shooting @ 15 yards and can hardly hit the 6” target at 20 yards. I am using Winchester 115 gr. FMJ. I don’t think it should be necessary to adjust my POA to hit the target. Is there something I’m doing wrong or have there been complaints of these guns shooting low? Do I need to return the gun or move to a different grain bullet? I am dead on when shooting my brother-in-laws XDm 9, and he is shooting low as well with my SD 9. Any suggestions would be very much appreciated.
