So I finally got my permit and took my new G27 out to shoot. I put 50 rounds through it and it was shooting really low. This is not the first time Ive shot a handgun and never shot this bad before. At about 10 yards i was hitting almost off the paper. The gun is brand new with Glock night sights. I have a feeling it is a problem with me and not the gun. i was shooting standing and using a 2 hand grip. I wont be able to shoot again for a few days to try and work it out but it is bugging me trying to figure it out. Next time i will shoot from the bench and see what happens.
