Frequently Asked Questions

Will this magazine fit my Beretta PX4 Storm compact or subcompact model?

This magazine is designed specifically for the full-size Beretta PX4 Storm chambered in .40 S&W. While it may fit PX4 Compact models with an extended grip, it is not designed for flush-fit use in compact or subcompact variants. Always verify compatibility with your specific firearm model before purchasing.

What does "17-round body, 10-round capacity" mean?

This magazine uses a standard full-capacity 17-round body that has been permanently blocked to comply with California's 10-round magazine limit. The physical size and profile of the magazine remain identical to the original, ensuring a perfect fit in your PX4 Storm, but it is restricted to hold a maximum of 10 rounds as required by California law.

Is this a genuine factory Beretta magazine or an aftermarket product?

Yes, this is an authentic OEM Beretta magazine manufactured to Beretta's strict quality standards and tolerances. Factory magazines are always recommended over aftermarket alternatives, as they are engineered specifically for your pistol and help ensure reliable feeding, proper lock-up, and consistent ejection with every round fired.
