Hi Joe, the problem could stem from a number of issues.. most of the time it is because the mag shell has deformed or grown across the width, or less common, the length front to back, just from use and time being constantly loaded.. this also seems to occur at the bottom of the shell, as well as the top.. Other times it is interference between the follower button and the grip or frame.. and occasionally just a deformation in the front spine.. Or a slight twist in the shell. I can remedy most of these ailments, as can several other forum members, who have the right tools.. The real trick to repairing an issue like a tight fit, is to do the repair and leave no tracks.. Luger mags show every tap and touch, they get mangey real fast!
I will repair to spec. and return ship for $25.00 total, most members find this agreeable, and I've repaired quite a few for the forum members that were real train wrecks!!
But most have been a bit less involved.. all seem to have been satisfied... Soooo, if you want me to work on it, just send it to:
