This KP90 pairs a matte stainless slide with a matte gray anodized aluminum-alloy frame for a durable, two-tone finish. It is a full-size .45 ACP with a 4.5" barrel and an 8+1 single-stack capacity, made in the United States in 2000.
It represents the early P-Series smooth-slide configuration without grasping serrations. Controls include a slide-mounted ambidextrous safety/decocker and an exposed ring-style spur hammer, with DA/SA operation for versatile handling.
Sights are straightforward and robust: a fixed setup with a ramped front blade featuring a white dot and a drift-adjustable rear notch for windage. Black checkered polymer grip panels with Ruger medallions provide a secure, serviceable hold.
The pistol retains the clean dustcover profile and lacks an accessory rail, consistent with this period of P90 production. The slide carries the Southport, Connecticut, U.S.A. rollmark address. Included steel single-stack magazines are compatible with Ruger P-Series .45 ACP models that share the P90 pattern.
