I recently bought and older loaded champion, and love the gun. I have had no problems out of it except a couple of failure to feeds, but i think that is due to the magazines. Anyway it has the fixed novak night sights, and it seems to be shooting 2 to 3 inches high. I have not actually put it on paper yet. I have been shooting anywhere from 10 to 20 yards with it. Is this normal? And is there anything i can do about it short of replacing the sights or do i just need to learn to hold the correction everytime? Thanks!
