The Springfield Armory Saint Victor 9mm 5.5" Pistol delivers premium AR-platform handling and large-format firepower in Springfield's most ultra-compact personal defense layout. Chambered in 9mm Luger, this modern specialty handgun runs on a rugged direct blowback system designed for absolute reliability across long training sessions. Both the upper and lower receivers are meticulously forged from high-strength 7075-T6 aluminum and stabilized utilizing an integrated Accu-Tite™ tension system to prevent cross-receiver play. Hidden beneath its free-floating aluminum M-LOK® handguard sits a compact 5.5-inch chrome moly vanadium barrel treated with a durable Melonite® finish. The muzzle comes factory-capped with a recessed SA Muzzle Drum forward-blast diverter, which pushes concussion waves cleanly forward away from the shooter. Equipped out-of-the-box for high-performance customization, the STV95509B configuration is outfitted with an adjustable SB Tactical SBA3 pistol brace on a 3-position receiver extension, an enhanced nickel-boron coated flat face match trigger, and an ergonomic B5 Systems Type 23 grip. It feeds directly from heavy-duty steel 32-round Colt®-pattern magazines.
