What’s Included

- Two 7-round single-stack steel magazines with witness holes

The P90 pairs an investment-cast stainless slide with a matte gray metal-alloy frame, delivering the stainless-slide KP90 variant look and feel. Controls include an ambidextrous push-button magazine release, exposed spurred hammer, and ambidextrous slide-mounted safety/decocker levers with a red fire indicator.
Its 4.5-inch barrel uses a bushing-less barrel/slide interface, and the slide features an enlarged ejection port. The single-stack design provides a 7+1 capacity in .45 ACP, and this example comes with two steel magazines equipped with witness holes.
Sighting is straightforward and durable with fixed 3-dot sights: a ramped front with a white dot and a dovetailed rear. The wraparound black rubber grip with Ruger medallion and finger grooves is installed, offering a secure, hand-filling hold.
Made in the USA in 2004, this discontinued P-Series service pistol holds niche collector interest while retaining the practical features associated with Ruger’s P-Series lineage.
