Ruger P91DC .40 S&W Full-Size P-Series, Two-Tone Stainless/Gray, 4.5 in Barrel, 11+1
The Ruger P91DC is a full-size, .40 S&W P-Series pistol with the decocker-only "DC" configuration, built in the United States in the 1990s. This example pairs a stainless slide with a matte gray aluminum alloy frame for a durable two-tone finish. It features an open-top slide, ambidextrous decocker levers, an ambidextrous magazine release behind the trigger guard, and fixed 3-dot sights with a windage-adjustable rear.
With a 4.5 in barrel, 11+1 capacity, and wraparound textured rubber grips with finger grooves, this P91DC offers solid handling in a straightforward DA/SA setup. The slide is marked "RUGER P91DC," and the barrel hood is marked ".40 AUTO" and bears the Ruger proof symbol—clear, correct markings for this model and era.

The P91DC uses a short-recoil, tilting-barrel action with a DA/SA trigger, paired to a decocker-only system via slide-mounted ambidextrous levers. The ambidextrous magazine release is positioned behind the trigger guard for easy access with either hand.
Construction is two-tone with a stainless slide and a matte gray aluminum alloy frame. The open-top slide design aids ejection, while the wraparound textured rubber grips with finger grooves provide a secure hold. An integral lanyard loop at the butt is included.
Sights are a fixed 3-dot set with a pinned front blade and a dovetailed rear adjustable for windage via a screw. The 4.5 in barrel chambered in .40 S&W and 11+1 capacity deliver full-size service dimensions in the P-Series format.
Markings are correct for the model and caliber: the slide is roll-marked "RUGER P91DC," and the barrel hood is marked ".40 AUTO" and stamped with the Ruger proof symbol. This U.S.-made example represents the 1990s-era P-Series design and feature set.
