Ruger P90 .45 ACP Semi-Auto, Full-Size P-Series, 4.5-inch Stainless Barrel, DA/SA, 8+1, 1999, USA
This Ruger P90 is a full-size .45 ACP from 1999, made in the USA and built on the P-Series platform. It pairs a 4.5-inch stainless steel barrel with an investment-cast aluminum-alloy frame for durability with manageable weight. The pistol uses a DA/SA operating system with a slide-mounted safety/decocker and comes with three 8-round magazines and the original Ruger hard case.
The P90’s control layout is straightforward and familiar, with a left-side push-button magazine release and an external ring hammer. The DA/SA trigger system supports both double-action first shots and single-action follow-ups, and the slide-mounted safety/decocker adds an additional control many shooters prefer.
Construction centers on a robust, investment-cast aluminum-alloy frame matched to a stainless steel 4.5-inch barrel. Molded polymer grip panels with vertical ribs and Ruger eagle medallions provide a secure, consistent hold.
Sighting is clean and simple with fixed 3-dot sights: a single-dot front and two-dot rear. The single-stack magazine configuration yields an 8+1 capacity in .45 ACP. As a late-1990s P-Series example, this 1999-produced pistol delivers the classic Ruger P90 feature set in a straightforward, proven format.
