Design and key features

The SIG SAUER MCX SPEAR LT BRACED PISTOL arrives in a Full FDE finish and includes a folding brace and a single 30-round magazine. It features ambidextrous controls on the lower and an ambi charging handle—sensible choices for dynamic drills and left- or right-handed manipulation. At $2,099.99 it sits in the upper-mid price range for factory-built semi-auto pistols with premium components.

Barrel, twist rate, and ballistic considerations

This example is chambered in 300 Blackout with a 9″ cold hammer forged barrel and a 1:5″ twist rate. The short, cold-hammer-forged barrel provides durability and consistent harmonic characteristics important for accuracy, while the 1:5″ twist is well-suited to stabilize the heavier subsonic projectiles commonly paired with suppressors. If your mission set includes close-quarters maneuvering or suppressed shooting, this configuration offers an excellent balance of terminal performance and compact footprint.

Applications

300 Blackout excels in suppressed subsonic roles and also allows supersonic loads for longer reach. The MCX Spear-LT’s 9″ barrel is optimized for CQB, personal defense, and team roles where compact length and controllability matter most.

Ergonomics and operational notes

Ambidextrous lower controls and charging handle reduce transitions during malfunctions and support faster follow-up shots from either shoulder. The included folding brace adds storage and transport flexibility without adding excess weight. The build condition is described as excellent, indicating careful prior ownership and maintenance.
