The Beretta PX4 Storm Subcompact in 9mm is the smallest member of the PX4 family, designed specifically for maximum concealability. While it shares the same name and visual aesthetic as its larger siblings, it features a significant internal mechanical departure to fit its smaller frame.
Tilt-Barrel System: Unlike the Full Size and Compact models, the Subcompact does not use the rotating barrel system. Instead, it utilizes a traditional Browning-style tilting barrel system to accommodate the shortened 3-inch slide and barrel assembly.
Snap-Grip Technology: The pistol often comes with a "Snap-Grip" magazine extension—a fold-down finger rest on the baseplate that provides a full-hand grip when firing but can be folded up to minimize the pistol's "print" while holstered.
Ambidextrous Controls: It maintains the family's ambidextrous manual safety/decocker levers (Type F) and a reversible magazine release, ensuring it remains user-friendly for both left- and right-handed shooters.
Rugged Construction: It features a stainless steel barrel for corrosion resistance and a fiberglass-reinforced polymer frame.
Modular Sights: Despite its size, it uses a standard 3-dot sight system that is removable and adjustable, allowing for the installation of night sights.
