Construction is all stainless steel, including the frame, cylinder, and barrel, with a uniform satin/brushed finish.

The revolver is built on a round-butt N-frame and wears factory black S&W-logo rubber finger-groove grips.
Sighting equipment is straightforward and effective: a pinned ramp front sight pairs with an adjustable rear sight. The action is DA/SA with an exposed hammer, and this example includes the keyed internal lock positioned above the cylinder release.
Made in the United States, this 625-9 Mountain Gun delivers the well-known S&W .45 Colt configuration in stainless steel with the features enthusiasts expect from this series, including the tapered barrel, partial underlug, and adjustable sights.
