Rock Island Armory Stk150 Ultra Hc 9Mm 4.49 17Rd

The Rock Island Armory STK150 Ultra HC is a striker-fired 9mm pistol built for shooters who want reliable performance without the premium price tag. This aluminum-framed compact carries 17 rounds of 9mm capacity and weighs just 1.85 lbs—light enough for all-day carry, substantial enough to manage recoil naturally. The 4.49-inch barrel splits the difference between concealability and velocity, while the 1911-inspired grip angle gives you that familiar, controllable hold even if you're coming from the classic platform.

Rock Island engineered the STK150's aluminum grip frame to do double duty: it absorbs felt recoil better than pure polymer, yet keeps the gun affordable and nimble in the hand. The textured grip surface locks your hand in place during the draw and follow-up shots, and the semi-automatic action with a 3.0–7.0 lb trigger break keeps your shot breaks clean and predictable. Black anodized finish resists corrosion and blends into any holster or gear bag.

Whether you're training at the range, carry-ready for personal protection, or just want a no-nonsense 9mm that handles like it costs twice as much, the STK150 delivers practical capability. The fixed rear sight is integrated into an optic cover plate—giving you the factory irons while leaving room to mount red dot or reflex sights if you choose. At 7.79 inches long and 5.33 inches tall, it's compact enough to conceal comfortably but large enough to shoot with precision.
