US PALM Storm CAT4 5.56mm 11.5in 30rd Black Semi-Auto Pistol (HG0001000-1-AA-N)

The US PALM Storm CAT4 Pistol delivers uncompromising performance in a compact, maneuverable platform built for serious shooters. Engineered with premium materials and purpose-driven features, the CAT4 blends durability, precision, and adaptability into a pistol platform that excels in demanding environments.

At its core, the CAT4 features a cold hammer forged 4150 chrome-moly barrel for exceptional longevity and accuracy, paired with a Hiperfire EDT Designated Marksman Trigger for a crisp, consistent break. The mono-loc handguard system and full-length Picatinny rail provide a rigid, optic-ready foundation for customization, while full ambidextrous controls ensure seamless operation for any shooter. Whether for duty use, range performance, or defensive applications, the Storm CAT4 Pistol is built to perform when it matters most.

The US PALM Hurricane Hybrid Muzzle Device on the Storm CAT 4 is one of the rifle's standout design elements because it's built to do two jobs at once: flash suppression and recoil control. Instead of being just a standard birdcage flash hider or a straight compensator, it's a hybrid comp/flash hider with a very aggressive helical, twisted-prong design that follows the barrel's twist direction. That spiral geometry isn't just for looks - it helps redirect gases in a way that keeps the rifle flatter during fast follow-up shots while still helping break up muzzle flash.

The US PALM Storm CAT 4's full ambidextrous controls are engineered for shooters who demand speed, adaptability, and total command from either side of the rifle. Every critical touchpoint - from the safety selector and magazine release to the bolt catch/release and charging handle - is fully accessible without forcing the shooter to break grip or shift position. This creates a faster, more intuitive shooting experience whether you're running support-side transitions, working barricades, or performing rapid reloads under pressure.
