This Sig Sauer MPX-K represents the pinnacle of 9mm tactical firearms, combining battle-proven reliability with cutting-edge engineering. Built around Sig's revolutionary closed-bolt, short-stroke gas piston system, this pistol delivers AR-level reliability without the harsh recoil of traditional blowback designs. The heart of this system is its 4.5" cold hammer-forged barrel, treated with black nitride for durability and threaded 13.5x1 LH for immediate suppressor compatibility.
What sets this MPX-K apart is its thoughtful design tailored for real-world use. The full-length Picatinny rail accepts any optic you choose, while the M-LOK compatible handguard provides modern accessory mounting without adding bulk. Sig's Timney single-stage trigger offers a clean, consistent break that outshines factory triggers, giving you precision when you need it most.
The innovative PCB pivoting contour brace makes this one of the most compact yet functional 9mm platforms available. Folded, it collapses to a mere 16.5" for easy storage or transport, yet remains fully operational when deployed. Every control is perfectly ambidextrous - from the safety selector to the magazine release - because real weapons shouldn't favor either hand.
At just 5 pounds unloaded, with a 35-round capacity and Sig's legendary reliability, this is the ideal package for home defense, tactical training, or range use. It ships with one 35-round polymer magazine and all factory documentation, ready for its new owner.
