What’s Included

- Owner's manual
- Three 8-round steel single-stack magazines
The P90 is part of Ruger's P-Series and uses a Browning-type short-recoil, locked-breech system with a linkless cam. The barrel hood locks into the ejection port, and a cam lug under the chamber rides a separate steel camblock pinned in the frame to tilt and unlock. It is chambered in .45 ACP and feeds from single-stack 8-round magazines for an 8+1 capacity. The 4.5 in stainless steel barrel complements the robust build and straightforward operating system.
Controls are familiar and practical, including a DA/SA trigger, an ambidextrous slide-mounted safety/decocker, and a left-side push-button magazine release. Sights are fixed 3-dot, with a pinned front and a dovetailed, drift-adjustable rear to fine-tune windage.
The two-tone finish pairs a matte stainless slide with a matte gray hard-anodized aluminum alloy frame. Grip panels are black grooved polymer with Ruger eagle medallions for a secure hold and classic P-Series appearance.
Manufactured in the United States and marked "SOUTHPORT, CONN., U.S.A.," this KP90 is cataloged as Model 06622 on the case end label, aligning with its manual-safety configuration. The included factory case, manual, and three magazines round out a complete setup.
