Overview

As a purpose-built pistol for the .300 Blackout round, the springfield saint 300 blackout semi-automatic pistol with 9-inch barrel bridges the gap between rifle power and pistol portability. Its 9-inch barrel optimizes velocity for both supersonic and subsonic loads, while the carbine-length gas system ensures reliable cycling across a wide range of ammunition. The pistol features a free-floating M-Lok handguard, a GI-style flash hider, and an SB Tactical SBA3 stabilizing brace, providing a stable shooting platform without the need for a tax stamp. This model comes standard with a single-stage trigger, a flat-face trigger shoe, and a nickel-boron coated bolt carrier group for enhanced durability and smooth operation.
