The RIA STK100 pistol in 9mm with a black finish (brand part no. RCKI 56625) is a striker-fired duty pistol built for shooters who want a high-capacity, no-frills platform. Rock Island Armory chambers the pistol for a 17-round capacity through a 4.5-inch barrel, and the serrated black anodized aluminum slide provides a secure grip during manipulation. Fixed 3-dot sights support fast target acquisition, and the pistol runs without a manual safety for a streamlined draw-to-fire sequence. Among high-capacity semi-auto handguns, this STK100 configuration favors shooters who want maximum capacity at an accessible price.
