Frequently Asked Questions

Will this magazine fit all variants of the Beretta PX4 Storm in .40 S&W?

Yes. This factory Beretta magazine is designed specifically for the PX4 Storm pistol chambered in .40 S&W, including the full-size PX4 Storm model. Because it uses the standard 14-round body, it seats flush and locks up just like the original magazine that shipped with your firearm. Always verify your specific PX4 variant in your owner's manual if you are unsure.

Why does this 10-round magazine come in a 14-round body?

To comply with California's magazine capacity restrictions, this magazine is blocked internally to limit feeding to 10 rounds while retaining the original full-size 14-round body. This means the magazine maintains the same dimensions, grip feel, and flush fit as a standard PX4 .40 S&W magazine — you won't notice any difference in how it sits in the gun or feels in your hand.

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

This is a genuine, factory-original Beretta magazine manufactured to Beretta's strict tolerances and quality standards — not an aftermarket or third-party product. OEM Beretta magazines are recommended over aftermarket alternatives because they are engineered specifically for your firearm, ensuring consistent feeding, reliable lockup, and long-term durability with factory-spec components.
