What’s Included

The P90 uses a double-action/single-action trigger system with a manual-safety/decocker configuration and a firing pin block. Ambidextrous slide-mounted levers and a red fire indicator dot provide clear, consistent control. The standard left-side push-button magazine release complements its single-stack 8+1 capacity.
Construction centers on an aluminum-alloy frame with a matte light-gray anodized finish paired to a dark slide for a purposeful two-tone appearance. The 4.5-inch stainless-steel barrel is designed for longevity in .45 ACP, and the exposed spur (ring-style) hammer offers positive manipulation.
Sighting is straightforward and durable: a fixed three-dot system with a ramped blade front featuring a white dot and a dovetailed square-notch rear with white dots. The slide includes dovetailing for the rear sight and ambidextrous safety/decocker levers. The dust cover is clean with no accessory rail.
Part of Ruger’s metal-frame P-Series, the P90 was introduced in 1991 and discontinued around 2010. This example was manufactured in 2005 in the United States, consistent with the 663 serial prefix timeframe for that year.
