I bought some of the ProMag 15 rounder's and bent the feed lips in some and they work great. Mine is a 9mm. I did the same for a friend's .40 cal and it feeds like it should. Sadly he's selling his due to unemployment. They are 2 of the fun guns to shoot.My Hi Point is the funnest thing to shoot I own. Ridiculously accurate and just a blast to shoot. If it had a version with higher capacity everyone would have one.
