This is probably a beginners question, and I'm certainly not a beginner, but I'll ask it anyway. I have a FM Hi Power 9mm that I carry as a duty piece. I know that the problem is really not with the gun, nor is it a function problem. Just really annoying. I have the original mag and 2 MegGar mags. The problem is, when they are fully loaded (13rds) and inserted in the gun, the cartridges rattle in the mag. Is there anything I can do to help with this (problem). I've tried everything I know to do to no avail. I'm going crazy 🤪😵 I CAN'T STAND RATTLES!!!!!???
