The GP Arms LLC Patriot 1911 Double Stack pistol is built on a milled commander size frame with an extended dustcover that sports a picatinny rail, lightened optics ready commander slide, and bull barrel.


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

After years of feedback from our customers and several years of R&D, we have put together a totally made in the USA with American parts 1911 Double Stack platform that we believe will be unmatched in quality, performance, aesthetics, with an attractive price.

The Patriot is available in a 4.1” bull barrel, a 4.1” ported bull barrel and 4.8” threaded bull barrel version.  These three variants take the proven 1911 platform to the next level of performance and versatility.

The GP Arms LLC Patriot comes with a lightened slide that has front and rear cocking serrations, match grade bull barrel, optics-ready, rear sight integrated RDS plate, and black post serrated front sight. 

With ambidextrous thumb safeties, 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 is a very capable and performance producing pistol.

The GP ARMS LLC Patriot sports a milled 416 stainless steel picatinny railed frame with an ergonomically designed polymer grip module that offers a capacity of 20+1 in an MBX Extreme 9mm 1911 double stack 126mm magazine.  Optional 22-round MBX Extreme 9mm 2011 140mm magazines are also available. 

Designed for versatility and a wide range of applications, the GP ARMS LLC Patriot is ready to accept several of the most popular optical sight footprints available.  Our sight plates are machined from billet steel.  The RDS plates 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.  Optional Delta Point Pro footprint rear sight plate is also available. 

The GP ARMS LLC Patriot 9mm 1911 double stack pistol takes the 1911 platform to the next level and elevates it with increased capacity and unmatched performance.
