Customer Reviews

Fits and functions like the factory 14 round magazines. Review by Rusty
I purchased this magazine to increase the capacity of my P320. I have ran several magazines full of ammo through my pistol with zero issues. I would not hesitate to purchase another. Thanks. (Posted on 2/11/2020)
