I recently bought an S&W SD9 - I have put just under 300 rounds thru it and I am consistently shooting down and left. Im 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 dont think it should be necessary to adjust my POA to hit the target. Is there something Im 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.
