United Gunworks UG-1 Alpha 9x19mm, 4.5" Ported Island Barrel, Aluminum Grip, Railed Frame, Flat Trigger, 1x 19 Rd Magazine 2x 20 Rd Magazines, RMR/SRO Plate, Hard Case, Optic Not Included

The flagship. A full-size double stack built start to finish in Peoria, Arizona — 4.5″ match-grade ported island barrel, ultra-low-mass slide, full-size steel frame and a crisp 2–3 lb break.

The UG-1 Alpha is a double stack 9mm built around a simple idea: nothing is bought finished. Frames, slides and operational components are machined, hand-fit, finished and function-checked under one roof in our 60,000 sq ft facility.

Every Alpha is cut and fitted to order. That is why there is a lead time, and it is why two pistols off the same line feel the same in the hand.
