Some things that can cause mags to hang up:
1) Bowed or flared magazine walls
2) Burrs on the trigger bow or one that is a little too flattened and protruding into the magwell
3) Magazine release has burrs, excess flashing (if they're MIM parts) or catch lip too wide
4) Magazine lips damaged or flared outwards too much
5) Disconnector protruding into magwell
6) Grip bushing screws too long and protruding into the magwell
Grab a sharpie and colour one of the mags. Remove the slide and insert the mag slowly while visually looking to see if anything is rubbing against the mag as you feed it into the magwell. Remove and insert the mag a few times. Does a full and empty mag drop cleanly with the slide removed?
Look and see if there are any rub marks on the mag after doing the above. If so, post a pic.
