SIG Sauer P320MAX Custom Works 9mm Luger, Full-Size, 5 in Match Bull Barrel, TXG TXG XFULL Grip, ROMEO3 MAX Red Dot, 21+1
The SIG Sauer P320MAX Custom Works is a full-size 9mm built for performance, pairing a factory direct-mounted SIG Sauer ROMEO3 MAX red dot with a 5 in match-grade bull barrel and a stainless slide finished in Nitron. Its TXG tungsten-infused XFULL grip module with flared, detachable magwell and aggressive stippling delivers a steady, competition-focused hold, while the 21+1 capacity keeps you shooting longer between reloads.
The 5 in carbon steel bull barrel is match-grade for consistent accuracy. A stainless steel slide wearing a Nitron finish adds durability and features wrap-around serrations for confident manipulation. The slide carries Max Michel logos and is configured with no iron sights to present a clean, red-dot-only sighting setup.
The TXG tungsten-infused polymer grip module provides added mass and recoil control without sacrificing ergonomics. Its aggressive stippling and flared, detachable magwell support fast, sure reloads. An M1913 accessory rail on the dust cover accepts compatible lights or other rail-mounted accessories as needed.
Inside, a striker-fired action combines with a flat, skeletonized trigger for a crisp, consistent pull. A one-piece steel guide rod is compatible with 1911-style recoil springs, and the modular P320 FCU chassis underpins the system. Controls are on the left side (slide catch, takedown lever, magazine release). The pistol is marked Newington, NH, USA.
