The P90 is a hammer-fired DA/SA design using a short-recoil, tilting-barrel system. Its slide-mounted ambidextrous manual safety also functions as a decocker, and the external spurred hammer provides clear status and deliberate control.
Construction is two-tone, pairing a stainless slide and stainless 4.5 inch barrel with a matte gray hard-coated aluminum alloy frame. The pistol was manufactured in the United States and carries factory rollmarks including "RUGER P90" on the slide and "STURM, RUGER & CO., INC., SOUTHPORT, CONN. U.S.A." on the receiver.
Sighting is straightforward and durable, with a fixed white-dot front and a low-profile, drift-adjustable rear, forming a three-dot arrangement. Controls are ambidextrous at the slide, and the grip frame includes an integral lanyard loop at the heel.
Dimensions and capacity are well-suited to a full-size .45 ACP: 8+1 single-stack capacity, an overall length of approximately 7.75 inches, and an unloaded weight of about 33.5–34 ounces. Textured black Ruger-logo grip panels round out the handling features.
This example dates to 1993. The serial prefix 660 denotes the P90-series block, consistent with Ruger's P-Series lineage and configuration.
