The Model 25-13 Mountain Gun is built on Smith & Wesson's N-frame in a round-butt configuration and is chambered in .45 Colt. It uses a six-shot fluted cylinder and a double-action/single-action system, combining a classic big-bore chambering with a balanced 4-inch barrel length.
The barrel is a tapered 4-inch design with a half-length ejector-rod shroud and a serrated rib. The topstrap has a matte, anti-glare bead-blasted finish. The frame, barrel, and cylinder wear a bright polished blue finish over carbon steel construction.
Controls and internals include a frame-mounted firing pin, a modern scalloped cylinder latch, and an internal key lock. The hammer and trigger are MIM components. Sights consist of a plain black ramp front and a micrometer-adjustable rear.
Factory markings are correct for this configuration: "Mountain Gun" legend on the barrel, ".45 COLT CTG." barrel marking, and "Model 25-13" marked on the yoke cut. This example corresponds to Smith & Wesson product code/mfg part number 160929 and was made in the United States.
