I recently purchased 2 XD40 mags and I am having trouble getting them to go more than half way into the handle when loaded with 12 rounds, they will go fine with 11 rounds. I did some searching on the site and think I found some ideas about how to fix but want to ask anyone that had a similar problem to make sure. I am assuming that round #12 is not seating deep enough down in the mag therefore causing the lips to bulge out and that is why they won't go in all the way. Do I need to bend the lips in until the round seats right in the mag? Thanks for your help.
