Hi V, that is a rare problem, but it does come around from time to time.... There is something you can do to help, and possibly correct the problem.. What I'm about to outline for you seems counter productive, but it works and you can easily try it yourself. First, you must acquire a round bar, or drill bit that is 13/32" or exactly .404" dia. Next, you clamp it (on the flutes) in a vice, or to a very heavy surface as you are going to use the shank as an anvil and forming tool both. Now, you have to probably take the mag apart to do the next step, but you can push the mag onto the shank depressing the follower at the same time, still, it is easier to just take it apart so you do not have too fight the pressure. Any way, you need to slide the front radius part of the mag onto the drill bit shank until it is past the mag catch notch. Then, using some very clean sheet aluminum, or very clean spring steel, you gently tap on it, the aluminum, with a small hammer, and with that, the mag shell on the front spine area adjacent to the mag catch, and this will cause the front radius to grow internally, with the end result is the sheet metal mag shell will better fill the void allowing it to drop free... The main concerns are, not to hit so hard you move metal, and not to overdo the expansion part of the process.. You can measure, or compare the gain from the rest of the magazine by looking at it from the back... In essence, you are expanding the magazine front radius from the outside, rather then from the inside... Good luck with the above... and, if not your cup of tea, I'm pretty much always here... best to you V,
