The TXG tungsten-infused polymer grip module adds weight to the frame to help reduce muzzle rise and speed follow-up shots. It is the full-size X-Series module in Legion Gray, with textured panels and SIG medallions for a secure hold.
The 5-inch carbon steel bull barrel and solid steel guide rod with 1911-pattern springs provide a smooth recoil impulse. A removable, flared magazine well (retained by a rear screw) supports fast, confident reloads.
The stainless slide wears a Legion Gray PVD finish and features front and rear cocking serrations plus three top lightening windows. Its R2 direct-mount optics interface supports SIG ROMEO1PRO and Leupold DeltaPoint Pro footprints; a factory SIG ROMEO1PRO is installed. A green fiber-optic front sight is included, and Dawson Precision replacement rods are provided.
Controls include bilateral slide-catch levers and a left-side takedown lever. The flat, skeletonized X-Series trigger offers a consistent, straight-press feel. A full-length Picatinny accessory rail is integrated into the dust cover. Capacity is 17+1 in 9mm Luger, with three magazines included. The frame is marked NEWINGTON, NH, USA.
