I took my P365XL grip with the SAS slide to the range -- at 5 yards and 7 yards my rounds are hitting slightly to the left; I go to 10 yards, my rounds are hitting half way between the center and the left side of target (IDPA cardboard) at 15 yards the shots are hitting at the left hand side and off the cardboard -- I go back to the standard slide -- center mass hits every time. think I will stick to the standard slide. shot 150 rounds; 72 with the SAS slide.
