I bought five 17 round glock mags to carry on duty, and 1 won't drop from the gun. It looks like its rubbing on the right side of the mag well, anyone else having this issue? Did I just get a lemon that swelled a little? will some sanding on the mag take care of the problem?
Most of my G9 15's don't drop free from my Polymer 80 when loaded. I wrapped one in blue tape a bunch, then heated the grip with a heat gun and shoved the mag in the gun. Once cooled, pull the mag out, untape, and fall she goes.
