Item # 256671 Style PM400-SDI-11B-BLK UPC 798681698967 Condition New Manufacturer [Sig Sauer](https://www.kygunco.com/brand/sig-sauer) Model SIGM400 Round Capacity 30 Caliber 5.56 NATO Action Semi-Auto Barrel Length 11.5 in The M400-SDI X Pistol has been developed with the input from the professional instructors at SIG SAUER Academy. Building upon their decades of experience and countless hours of instruction, we have developed the M400-SDI X Pistol to meet the highest standards of performance and reliability. With fully ambidextrous controls including a bolt catch/and release unique to the M400-SDI lower receiver, the M400-SDI X Pistol delivers advanced performance for both left & right-handed shooters and makes transitional shooting easier than ever. The free-floating handguard utilizes a new steel lockup design that significantly reduces handguard deflection by providing maximum rigidity and allows for accessories to be attached on all four sides with no effect on accuracy. The 2-Stage Matchlite Duo trigger provides an out-of-the-box crisp 4.5 - 6.5lb pull weight with a flat blade design for a precision feel. The M400-SDI X Pistol utilizes the highest quality performance coatings to ensure maximum durability and reliability. - Ambi Bolt Catch/Release, Safety Selector, Charging Handle, and Mag Catch - Low-Profile Gas Block with Carbine Length Gas System - 2-Stage Flat Blade Match Trigger - Free Floating M-LOK Handguard - Hybrid Compensator/Flash Hider - Magpul BSL Telescoping Brace ** WARNING: This product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
