The Beretta USA Px4 Storm Compact 10-round .40 S&W magazine is a factory original spare magazine built to the same exacting standards as the pistol itself. Whether you're stocking up for the range, adding backup capacity for duty or carry, or simply building a deeper rotation of reliable mags, this black steel magazine feeds .40 S&W rounds with the dependability Beretta is known for. At 10 rounds, it matches the standard capacity of the Compact model and gives you flexibility if you need extra firepower on the clock.

This is a straightforward, no-frills spare mag—the kind of accessory serious shooters keep on hand because downtime between magazines ruins practice sessions and costs precious time in the field. Factory Beretta magazines tend to outlast the shooter's interest in the gun, so investing in spares now means you'll have reliable feeding for years to come.

Note that this magazine will also function in the Px4 Sub-Compact .40 S&W, though it will extend below the grip when inserted into that shorter model. If you own both Compact and Sub-Compact variants, one magazine works across the lineup—just manage the fit to your use case.
