PRO MAG - Sig Sauer P320 Magazine 9mm 32-Rd

Tried these mags in two different sigs. The M17 bravo and the X5. Did the same on both, wouldnt allow the trigger to reset, and would jam and prevent slide from fully seating. On both weapons. Luckily, I bought them on sale. I didnt want to mess with it, so I just threw them into the metal recycling pile. This is the reason I mainly stick to factory made mags

It does hold 32rounds and technically fits in the gun. However; It will not let the trigger reset after each shot (Voluntary Sig Upgraded Gun.) You have to drop the mag to release the tension on the trigger transfer bar for it to reset. Also occasionally it would lock the slide open when it was still full of ammo. It is possible it might be able to be modified to work by polishing down the side of the magazine that contacts the effected internal parts. Or maybe the magazine catch hole is slightly too high. Either way, not reliable enough to be worth the cheap price.

Held 33 rounds, felt solid, but once a round was fired I had to eject the magazine to reset the trigger. Left unloading 33 rounds to reload my 17 round magazine at the firing line. I'm not a gunsmith but I didn't see any visible differences between the factory mag and these but they would not let the trigger recycle. Returned.
