Sig Sauer Mpx K Pmpx4b9 9mm Luger 4.5 inch 35+1 Hard Coat Anodized

The Sig Sauer PMPX4B9 MPX K brings the trusted MPX platform into a compact, hard-hitting 9mm Luger package that reads like a range-ready tool for home defense, competition, and truck carry alike, with a 4.50" cold hammer-forged carbon steel barrel and a reliable gas piston operating system that tame recoil and extend longevity. With a 30+1 capacity and a threaded M13.5 x 1 mm muzzle, the MPX K accepts common 9mm suppressors and compensators while its hard coat anodized receiver and black polymer grip deliver durable, low-maintenance handling. The folding, pivoting contour brace stock collapses for compact storage or transport and locks open to provide a stable cheek weld for rapid follow-up shots; a Timney single-stage trigger and 1:10 twist rate optimize consistency for both defensive loads and match-style ammunition. The alloy forend features M-LOK attachment points for lights or slings, overall length measures 22.25" and weight is about 5 lb for a balance of portability and control. This semi-auto firearm requires transfer through an FFL and appeals to shooters who want the MPX series� proven ergonomics and modularity in a short-barrel configuration.
