Developed by SIG Custom Works alongside champion shooter Max Michel, the P320MAX is purpose-built for competition. The slide is cut specifically for the ROMEO3 MAX optic and ships without iron sights, offering an optic-only sighting system tailored to open-style competition use.
The 5-inch match-grade bull barrel pairs with a one-piece steel guide rod and a 1911-style recoil spring system for tuned performance. From the factory, this model is configured to use 12 lb and 14 lb recoil springs. Wrap-around and top serrations, plus a forward chiseled nose, support secure, over-the-top manipulations.
Ergonomics are anchored by the XSeries full-size grip module with aggressive texture, a flared magwell for fast reloads, a beavertail, and an undercut trigger guard. A flat-faced, skeletonized trigger and a reversible magazine release round out the control set for a competition-ready feel.
This full-size, striker-fired 9mm includes four 21-round extended magazines to maximize time on the line. A full-length Picatinny accessory rail on the dustcover allows light or accessory mounting. The pistol is made in the USA and marked NEWINGTON, NH, USA.
