1 of 5 Defective/ Does not work with P320 March 28, 2021
Reviewer: Ruben from Miami, FL  
I’ve had this magazine for a few days in my home defense weapon and stupidly never tried to rack my gun until today. Good thing I did because it does not work. Gun stays in back position and can not go forward or pick up a bullet. Tried with the mags my gun came with and no problem. Most of the cost of this was shipping so it’s probably not worth my time to return. I’m writing this review because I’m angry that I could’ve been in a  bad situation and my gun wouldn’t have worked. At the very least don’t buy this if you have a P320
