Rock Island Armory announces newly redesigned models in the STK Series.
Rock Island Armory states “The STK Series by Armscor / Rock Island Armory is releasing its newly redesigned line, offering elevated craftsmanship, performance-driven updates, and premium materials. The STK100 Ultra, STK150, and STK200 bring new functionality and classic design together to deliver a truly advanced experience for concealed carry and everyday users.
The STK series stands out with its unique all-aluminum 7075 T6 frame construction—moving away from traditional polymer materials—and a refined 1911-style grip angle, ensuring comfort and control that firearms enthusiasts trust. With the addition of an extended beaver-tail, slide bite is eliminated, providing a smooth shooting experience across all models.
One of the most notable upgrades is the flat-faced trigger, optimized to deliver a crisp and responsive pull that many users already find superior to factory alternatives. The STK100 Ultra, the series flagship, includes more aggressive side grip panels and a checkered frame for added confidence. Designed for maximum speed and efficiency, the Ultra model integrates a new magwell for faster, smoother reloads.
“We’re thrilled to unveil the newly redesigned STK series, which honors the heritage of classic firearm design while embracing modern innovations and user-focused details. These updates bring a level of performance and control that truly stand out in today’s market,” said Martin Tuason, President and CEO of Armscor / Rock Island Armory.”
