So I went and shot my xd subcompact 9mm today at a new range in which they have steel targets. This means that I have to shoot lead free frangible bullets.. Remind you that this is the second time shooting this gun. I took their free basic course and went over hand grip position ect.. When I was in the range, I was shooting very well. One of the defensive instructors told my mom that the reason why I was having jams and misfires was because the way I was shooting the gun.. However the guy that I talked to prior said it was because the ammo was reloaded.. Any ideas about this?
