The 7.5-inch barrel is made from 416R stainless steel and treated with Melonite for surface hardness and corrosion resistance. A 1:7 twist supports a wide range of 5.56 NATO bullet weights. The gas system is direct impingement and semi-automatic.
The handguard is a free-float aluminum M-LOK design with an integral hand stop and a factory forward-blast diverter nested in the nose. It carries a "PAT. PEND." marking and a short 12 o'clock rail segment near the muzzle, while the receiver offers a flat-top Picatinny rail with T-marks for consistent accessory placement.
Forged 7075-T6 aluminum receivers are hard-coat anodized and include Springfield's Accu-Tite upper/lower tensioning system. The selector uses SAFE/FIRE pictograms, and the receiver is marked "MULTI-CALIBER." An M16-profile bolt carrier group and a single-stage, GI-style, nickel-boron coated trigger round out the core operating components.
The pistol wears a polymer, strap-type brace and a textured pistol grip. It is configured without sights. Capacity is 10+1 and it includes one 10-round Magpul PMAG. Built in the USA, this SAINT Pistol presents a feature-rich, compact configuration ready for rail-mounted accessories.
