Not sure if this is a gunsmithing question but I'm looking for some advice on making a pinned mag functional. I recently bought a few used 15 round pistol mags pinned to 10 rounds. Problem is the rivet sticks out just a little so the mags don't slide in to place - the rivet gets caught. I'm wondering how I can I fix this? Of course I'm concerned about messing with the rivet, cause if it falls out I have a prohibited item. Any thoughts or advice would be greatly appreciated. Thanks. I've attached a pic to show the mags.
