Hey guys, I have a .40 Tac and I just started to have major jamming issues with all ammo. I let a buddy of mine borrow my 2 12 rnd magazines a few weeks ago so he could have spares at the range. After I got them back I went shooting and this is where the fun started. I've always shot UMC, & WWB but this time I would chamber a round fire it, and the next round would try and chamber but would get jammed pointing straight up every time. When I checked my magazines they looked slighty tampered with. The magazines were tight around the ass end of the casings but loosened up around the rest of the bullet (basically making a "door hinge" effect). I called my buddy up and he said he was having trouble with shooting his reloaded ammo and said he had bent the mag lips a bit. :evil: I was extremely pissed at this point and told him he owes me 2 new magazines. I tried to bend them back the best I could but nothing seems to fix my problem. Do you guys think that having a bad magazine would cause the problem I'm having?
