The Smith & Wesson Model 617 Mountain Gun is a Lipsey's exclusive K-Frame revolver that brings the traditional Mountain Gun tapered barrel profile to the .22 LR platform — featuring a 4.125" half-lug tapered stainless steel barrel that sheds 3 to 4 ounces compared to the full-lug 617, delivering a more natural balance and carry-friendly profile while retaining the all-stainless construction and 10-round cylinder that define the modern 617 series. The revolver introduces several meaningful refinements over standard 617 production including the elimination of the internal lock, a yoke-based lockup system in place of the traditional ejector rod lock, flash chrome finished trigger and hammer for corrosion resistance, and a gold bead Patridge-style front sight paired with a fully adjustable rear sight for precise target work at any distance. Completing the package are Tyler Gun Works high-grade walnut Bear Hug grips that complement the brushed stainless finish and provide ergonomic control through the smooth DA/SA action — all at 36.1 oz and 9.46" OAL.
