GP Arms Patriot 4.8 Threaded Barrel


GP ARMS is excited to announce the release of the GP ARMS LLC 1911 Double Stack “Patriot” line of pistols.

After extensive customer feedback and years of R&D, we proudly present a 1911 Double Stack platform made entirely in the USA with American parts. The Patriot line promises unmatched quality, performance, aesthetics, and an attractive price.

Available in three variants—4.1” bull barrel, 4.1” ported bull barrel, and 4.8” threaded bull barrel—the Patriot enhances the proven 1911 platform with superior performance and versatility.

The Patriot features a lightened slide with front and rear cocking serrations, a match-grade bull barrel, optics-ready design, rear sight integrated RDS plate, and a black post serrated front sight.

Equipped with ambidextrous thumb safeties, a 1/4” solid steel full-length guide rod, flat wire chrome silicon spring, shouldered reverse plug, match-grade fire control system, flat skeletonized trigger, and aluminum tactical magwell, the Patriot delivers exceptional performance.

The Patriot boasts a milled 416 stainless steel picatinny railed frame with an ergonomic polymer grip module, offering a 20+1 capacity with an MBX Extreme 9mm 1911 double stack 126mm magazine. Optional 22-round MBX Extreme 9mm 2011 140mm magazines are also available.

Designed for versatility, the GP ARMS Patriot is compatible with several popular optical sight footprints. Our sight plates, machined from billet steel, come in RMR, RMS-C, and Delta Point Pro footprints.

The pistol ships with either the RMR footprint rear sight plate and cover plate or the RMS-C/Holosun 407K-507K footprint rear sight plate and cover plate. An optional Delta Point Pro footprint rear sight plate is also available.

The GP ARMS Patriot 9mm 1911 double stack pistol elevates the 1911 platform with increased capacity and unparalleled performance.
