I've only had good luck with Pro-Mag magazines in my Beretta 92FS and my Kel-Tec SUB2000 that takes the same mags. I had to tweak the lips a little on both of them, and the baseplate extentions on both were screwed on crooked. After rescrewing the baseplates and doing a little pliers work on them, they worked fine. But I've never had a single issue with the Meg-Gar mags I've had in almost every other gun I've had.
