I recently bought a Sig P320 Compact with SIGLITE Night Sights. It currently has a #6 front sight and #8 rear sights. I've taken it to the range a few times now and it seems like the gun is always shooting low. Even today, I took it to the range and had to aim pretty high in order to hit the steel targets. Is this to be expected from my P320 or is it possible that I am doing something wrong? I am a newer shooter and it's definitely possible that my form or sighting could be off, so any tips would be helpful. I have had a couple of other more experienced shooters try shooting the gun and they also were shooting low. As far as my sight picture goes, I've tried aiming with a 6 o'clock sight, a center hold sight and a combat frame hold sight .. I just can't seem to hit the target without aiming well above the target. Any suggestions would be appreciated. Thanks!
