Beretta PX4 Storm .40 S&W 17-Round Magazine

This is a Beretta PX4 / CX4 .40 S&W 17-round extended magazine.

Featuring blued steel construction with oversized polymer baseplates and numbered witness holes, these factory replacement magazines give you a few extra rounds without adding too much height to the gun—making them the ideal choice for home defense, where you won’t always have a spare magazine handy.

Beretta’s NATO-approved PX4 Storm features a unique rotating barrel assembly that helps mitigate recoil from the powerful .40 S&W cartridge, while keeping you on target for faster follow-ups.

They’re also compatible with PX4 Compact pistols chambered in .40 S&W, CX4 carbines chambered in .40 S&W and equipped with the PX4 magazine well insert/release.

Remember that extended magazines are still susceptible to wear and tear, so be sure to rotate them regularly.
