THRiL PMX SM9 9mm Luger 35rd Magazine for Sig MPX Gen II Gray

The THRiL PMX SM9 is a Generation 2 9mm Luger polymer magazine purpose-built for the Sig Sauer MPX Gen II pistol-caliber carbine. With a 35-round capacity housed in a gray polymer body, the SM9 delivers a high-capacity upgrade or direct replacement for factory MPX-pattern magazines.

THRiL builds the SM9 with stainless steel feed-lips for reliable feeding and resistance to deformation, an improved follower design for smoother round presentation, and a stability rib running along the rear spine that stiffens the magazine body under repeated insertion and hard use. The lightweight polymer shell keeps the magazine light for extended range sessions.

Engineered as a drop-in fit for Sig MPX Gen II magazine wells, this package includes one (1) 35-round 9mm Luger magazine.
