Springfield Saint 300 Blackout Semi-Automatic Pistol with 9-Inch Barrel

The Springfield SAINT 300 Blackout Semi-Automatic Pistol with 9-Inch Barrel represents a precision-engineered platform for shooters who demand compact maneuverability with the ballistic versatility of the .300 Blackout cartridge. Built on Springfield Armory’s proven SAINT platform, this pistol bridges the gap between a traditional handgun and a short-barreled rifle, delivering reliable semi-automatic function in a package optimized for suppressed and unsuppressed use. Designed around a 9-inch barrel, this model maximizes powder burn for supersonic loads while maintaining quiet operation with subsonic ammunition.

Overview

The springfield saint 300 blackout semi-automatic pistol with 9-inch barrel is chambered in .300 Blackout, a cartridge known for its ability to switch between supersonic and subsonic loads without modification. The SAINT pistol utilizes a direct impingement gas system with a carbine-length gas tube, tuned specifically for the .300 Blackout pressure curve. The 9-inch CMV barrel features a 1:8 twist rate, stabilizing both heavy subsonic projectiles and standard supersonic rounds. A free-floating M-Lok handguard with a full-length Picatinny top rail provides ample mounting space for optics and accessories while keeping the overall profile slim and lightweight. The pistol is equipped with a SB Tactical SBA3 adjustable arm brace, allowing for improved stability during aiming without requiring a tax stamp. The lower receiver includes an enhanced trigger group with a polished trigger face and a crisp 4.5-5.5 pound break, reducing shooter error during rapid fire.
