This is Beretta's factory replacement magazine for the PX4 Compact in .40 S&W, a 12-round blued steel unit that also fits the PX4 Storm Compact and the PX4 Sub-Compact in the same caliber. It is the standard-capacity magazine for the Compact grip frame, so it seats as the pistol was designed and feeds with no extension or adapter involved.

New Jersey shooters should read the capacity before ordering. At 12 rounds this magazine sits above the 10-round line, and magazines over 10 rounds cannot be delivered to a New Jersey address. It remains the right spare for a PX4 Compact owner shipping to an address where the law permits it. As a factory part it keeps the spring, follower and feed lips matched to the pistol, which makes it the sensible choice for spares and for replacing a worn original rather than an aftermarket copy.
