The Springfield Armory Kuna Tri-Lug 9mm Large-Format Pistol with Strike Industries FSA Brace is an ultra-compact personal defense weapon engineered to deliver maximum stability while satisfying strict state-mandated magazine capacity limits. Built on Springfield's soft-shooting roller-delayed operating system, this platform temporarily locks the bolt into battery to shed significant reciprocating mass and drastically minimize felt recoil. The 6-inch cold radial hammer-forged Melonite barrel comes equipped with a 1/2x28 thread pitch and a factory multi-port muzzle brake, making it fully ready for smooth suppressor or muzzle device integration. It utilizes a durable Type III hardcoat anodized monolithic aluminum upper receiver paired with an injection-molded, glass-filled polymer lower housing that features completely ambidextrous controls. Ready for immediate duty out of the box, this package features a side-folding Strike Industries FSA pistol brace anchored to a Picatinny end plate, built-in hybrid flip-up metal sights, and two 10-round translucent magazines with steel feed lips.
