This is a .40 S&W factory 10-round magazine for use with Beretta Px4 Storm pistols where standard magazines are prohibited, including (but not limited to): CA, CO, CT, HI, MD, MA, NJ, NY
Beretta’s Px4 Storm features a rotating barrel that helps mitigate recoil from the powerful .40 S&W cartridge while keeping you on target for quicker follow-ups.
These 10-round magazines will keep you compliant with capacity laws in most states, while fitting flush and feeding the powerful .40 caliber cartridge reliably from your full-sized Px4 Storm. Don’t forget to rotate your magazines regularly, and always keep a spare on hand.
Also compatible with .40 S&W Cx4 Storm carbine (with Px4 magazine well insert/release), Px4 compact & sub-compact (extends below base of grip).
