The Rock Island Armory STK150 Ultra HC pistol in 9mm with a 17-round capacity (brand part no. 56611) pairs a striker-fired action with an aluminum grip that adds just enough weight to reduce felt recoil while staying comfortable for all-day carry. Armscor/Rock Island Armory textures the grip and angles it like a 1911 for greater control, and the patent-pending frame delivers the durability of metal at a polymer-comparable price. The 4.49-inch barrel pairs with a front sight tenon cut with a retaining screw and a fixed rear sight integrated on the optic cover plate, and the black anodized finish rounds out the package. Among aluminum-gripped semi-auto handguns, this STK150 Ultra HC configuration favors shooters who want metal-grip durability with reduced felt recoil.
