Beretta PX4 Storm Magazine 40 S&W 12-round

PX4 Compact .40 Magazine

This is a factory Beretta magazine for the PX4 Storm Compact in .40 S&W, holding 12 rounds. It is OEM, meaning Beretta made it for its own pistol rather than an aftermarket company copying the pattern, so fit and feeding match the gun as it left the factory. PX4 Compact owners use it as a spare for the range, a carry reload, or a replacement for a worn original.

Features

• Factory OEM Beretta — Made by Beretta for the PX4 Storm line, carrying manufacturer part number JM88404.
• .40 S&W Caliber — Built for the .40 Smith & Wesson cartridge only, so it will not interchange with 9mm PX4 magazines.
• 12-Round Capacity — Holds twelve rounds of .40 S&W when fully loaded.
• PX4 Storm Compact Fit — Sized for the Compact frame of the PX4 Storm, so check your model before ordering.
• Steel Body — The magazine tube is steel with a black finish, stiffer than polymer and resistant to swelling or splitting at the feed lips.
• Heat-Treated Steel Spring — The wire spring that drives rounds upward is heat treated to hold its tension through repeated loading.
• Orange Polymer Follower — The follower, the platform that sits under the rounds and pushes them toward the chamber, is bright orange so an empty magazine is easy to spot.
• Polymer Base Plate — A black polymer floor plate closes the bottom of the magazine and can be removed for cleaning.

Build And Fit

The steel tube has a formed reinforcing rib down the side and a cutout near the top, with the polymer follower and base plate fitted at each end. It is the 12-round .40 S&W magazine for the PX4 Storm Compact. Full-size PX4 pistols and 9mm models take different magazines, so confirm your caliber and frame size before you buy.
