This is a .40 S&W COMPACT factory 12-round magazine for Beretta PX-4 Storm compact pistols
Packing 12 rounds of powerful .40 S&W and a rotating barrel designed to mitigate the cartridge’s stiff recoil, Beretta’s Px4 Storm Compact is a force to be reckoned with.
These .40 S&W factory replacement magazines are manufactured to Beretta’s exacting specifications and tolerances for reliable feeding. They’re compatible with Px4 Storm Compact and Subcompact pistols (extends beyond base of smaller pistol), but they’re NOT compatible with full-sized Px4 Storm pistols or Cx4 Carbines.
Especially for concealed carry magazines, remember to rotate them regularly and always keep a spare on hand.
