Smith & Wesson Model 25-13 Mountain Gun .45 Colt, 4-inch Blued N-Frame DA/SA Revolver
This Smith & Wesson Model 25-13 Mountain Gun is a .45 Colt N-frame revolver with a 4-inch tapered barrel and a short underlug, built from blued carbon steel with smooth hardwood round-butt grips. It features adjustable iron sights with a pinned, serrated ramp front, a smooth-faced trigger, and a checkered hammer spur. The barrel is roll-marked 'Mountain Gun' and '.45 COLT CTG,' and no internal key lock is visible above the cylinder latch.
The N-frame, six-shot fluted cylinder and DA/SA action deliver the classic large-frame S&W configuration in .45 Colt. The tapered 4-inch barrel pairs with a half-length ejector-rod shroud, and the topstrap is serrated to reduce glare. The ejector rod has a knurled tip for positive purchase.
Controls and sighting equipment include a pinned, serrated ramp front sight, an adjustable rear sight, a smooth-faced trigger, and an exposed hammer with a checkered spur. The revolver wears smooth hardwood grips on a round-butt frame for a straightforward, traditional feel.
Factory markings are present throughout: Model 25-13 on the yoke cut; S&W trademark logo on the right sideplate; frame marked 'MADE IN U.S.A. MARCAS REGISTRADAS SMITH & WESSON SPRINGFIELD, MASS.' Additional details include a serrated topstrap and assembly number '333' on the yoke. Country of origin is the United States.
