US Palm Cat4 Storm 5.56 NATO 11.50" 30+1 Semi-Auto Pistol

The US Palm CAT4 Storm is a compact semi-auto pistol chambered in 5.56 NATO, built around an 11.50" barrel. Part of US Palm's Storm series, this pistol is finished throughout in matte black and engineered with full ambidextrous controls for fast manipulation by either hand.

At the core is a cold hammer-forged 4150 chrome-moly steel barrel with a 1:7" twist and a threaded muzzle capped by US Palm's Hurricane flash hider. The matte black receiver is topped with a Picatinny rail for optic mounting and paired with an M-LOK handguard for accessory attachment. The Hiperfire EDT trigger delivers a clean, consistent break.

This configuration ships with an adjustable black polymer stock and US Palm's signature reduced-angle grip for improved ergonomics and recoil management. With an overall length of 29" to 32.30" and a weight of approximately 6 lbs, the CAT4 Storm is a compact platform. Sights are not included, allowing the shooter to outfit the optic of their choice on the integrated Picatinny rail. Capacity is 30+1 in 5.56 NATO.
