Sig Sauer MCX LTAW .300 BLK Folding Braced Pistol 6.75" Barrel - 30 Rd

Delivering elite close-quarters capability and low-visibility tactical performance in an ultra-compact footprint, the SIG Sauer MCX-LTAW .300 Blackout Pistol (SKU: PMCX-300B-6B-LTAW) brings LVAW-inspired engineering to SIG’s battle-proven MCX platform. Built around a short 6.75-inch cold hammer-forged carbon steel barrel with an ultra-fast 1:5" twist rate—ideal for fully stabilizing subsonic and supersonic .300 BLK projectiles—this modular semi-automatic pistol comes factory-equipped with a direct-thread training tube mounted over standard 5/8"-24 muzzle threads. Powered by a short-stroke gas piston system with an adjustable gas block, the MCX-LTAW ensures reliable cycling across diverse ammunition loads and suppressor setups.

Designed for extreme thermal management and seamless weapon manipulation, the pistol features an oversized alloy suppressor-compliant handguard lined with an integrated full-length internal heat shield that isolates high barrel and suppressor temperatures from the operator's support hand. Built with standard MCX LT fully ambidextrous controls, a two-stage match duo trigger with a curved bow, and an MCX Legacy angled polymer grip, the MCX-LTAW offers intuitive control for both right- and left-handed shooters. Complete with a push-button folding PCB pistol brace that collapses total overall length down to an ultra-portable 22.5 inches and a 30-round Magpul PMAG Gen M3 300 BLK magazine, this 7.0-pound pistol is a refined, purpose-built tactical solution.
