SIG SAUER P320 MAX 9mm Competition Pistol with ROMEO3 MAX

SIG SAUER P320 MAX Competition Pistol

The SIG SAUER P320 MAX is a full-size 9mm competition pistol engineered around the needs of Carry Optics shooters. Developed with input from champion shooter Max Michel, this factory-configured model combines a weight-forward tungsten-infused grip, a purpose-built Custom Works slide, a match-grade barrel, and a competition-ready SIG SAUER optic. It gives serious competitors a coordinated package without requiring them to assemble the core pistol, optic, recoil system, and magazine set one component at a time.

This listing is for manufacturer part number 320X5-9-MAXM, chambered in 9mm Luger. It includes the direct-mounted ROMEO3 MAX reflex sight and four 21-round steel magazines. The pistol uses the modular P320 fire-control system and a striker-fired action, while its full-size competition configuration emphasizes control, fast sight acquisition, and efficient manipulation through a stage.

Competition-Focused Construction

At the center of the P320 MAX is SIG SAUER’s TXG full-size XGRIP module. The tungsten-infused polymer construction adds meaningful mass compared with a conventional polymer grip, helping the pistol settle during rapid strings and making the overall balance more suitable for competition. The gray grip module incorporates an extended beavertail, an undercut trigger guard, an integrated magwell, and an M1913 accessory rail.

The stainless-steel Custom Works slide wears a black Nitron finish and uses prominent wrap-around serrations. These cuts provide multiple gripping surfaces for loading, clearing, and administrative handling from the side or top of the slide. A skeletonized flat trigger complements the competition-oriented setup with a straight trigger face and consistent finger placement.

Barrel and Tunable Recoil System

SIG SAUER equips this model with a 5-inch match-grade bull barrel made from carbon steel. The non-threaded barrel is paired with a solid one-piece stainless-steel guide rod. Both 12-pound and 14-pound 1911-style recoil springs are included, allowing an experienced competitor to select the spring that best matches the ammunition and operating feel desired. Any recoil-system changes should be tested for dependable function before the pistol is used in competition.

ROMEO3 MAX 6 MOA Optic

The included ROMEO3 MAX is mounted directly to the slide and uses a 6 MOA red-dot reticle. A larger competition-oriented window and readily visible dot are intended to support quick presentation and transitions between targets. Because the optic is installed as part of the factory configuration, the slide and sight arrive as an integrated system rather than as separate components that still require mounting.
