Does this happen with the factory mag or does it drop out? I got a Masen mag that was part of a bad batch that had the catch stamp on the mag slightly misplaced and they were hard to get to latach and release. (Masen replaced it)
I would compare the length from the top of the lip to the bottem of the catch stamp if this length is too long you can always file it down to factory length.
