A K-Frame .22 Built to Be Carried and Used
The Smith & Wesson Model 617 Mountain Gun is a carry-oriented version of the classic stainless-steel K-frame .22 LR revolver. This Lipsey's Exclusive combines a 10-shot cylinder with a lightweight tapered 4.125-inch barrel, round-butt frame, and listed 36.1-ounce unloaded weight. It is for the shooter who wants a serious .22 revolver that balances naturally in the hand and is pleasant to carry afield, keep in a kit, or shoot often at the range.
The Mountain Gun is not simply a standard Model 617 with walnut grips. Its tapered barrel and reduced forward weight move it away from the heavy full-underlug target-revolver feel and toward a more traditional field-revolver balance. It remains all stainless steel and substantial enough to shoot well, but without turning a .22 LR into unnecessary belt weight.
Why Choose the Mountain Gun Instead of a Standard 617?
The primary difference is how it carries and handles. A conventional Model 617 is an excellent rimfire target revolver, but its heavier barrel profile puts more weight forward. The Mountain Gun makes more sense for the buyer who values a quicker, more traditional K-frame feel and wants a .22 that is as enjoyable to carry as it is to shoot from a bench.
The tradeoff is equally straightforward: the lighter barrel profile gives up some of the steady, muzzle-heavy feel that can be useful for deliberate slow-fire target work. For a shooter who wants a dedicated bull-barrel rimfire for maximum range stability, the standard 617 may be the better fit. For someone looking for a useful field, trail, training, and all-around .22 revolver, the Mountain Gun is the more distinctive configuration.
A 10-Shot .22 LR for Real Practice
The 10-round cylinder gives the owner more useful shooting time between reloads than a traditional six-shot rimfire revolver. That makes the 617 Mountain Gun particularly well suited to double-action trigger practice, introducing newer shooters to revolver operation, informal target work, small-game use where lawful, and general range time without centerfire ammunition expense.
Like all rimfire firearms, ammunition choice still matters. Different .22 LR loads can produce different accuracy, point of impact, ignition consistency, and extraction behavior. Test several quality loads before settling on a preferred practice, field, or target ammunition.
Traditional Features That Matter
This version is built without Smith & Wesson's internal lock, preserving the clean traditional profile many revolver buyers prefer. It also includes Tyler Gun Works Bear Hug high-grade walnut grips, a gold-bead front sight, adjustable rear sight, flash-chrome trigger and hammer, ball-detent cylinder lockup, and a beveled cylinder.
The walnut grips and brushed stainless finish give the revolver an heirloom-quality appearance, but the practical details matter just as much. The adjustable rear sight allows the owner to refine point of impact for a chosen load, while the gold bead provides a fast visual reference for deliberate field shooting or normal range work.
Who the 617 Mountain Gun Makes Sense For
This is a strong choice for the shooter who appreciates the handling of a traditional K-frame and wants a premium .22 LR revolver that is easier to carry than a heavy target configuration. It is especially appealing to buyers who value the no-lock build, stainless-steel durability, real walnut grips, 10-shot capacity, and the balance of a tapered barrel.
It is less suited to someone seeking the lowest-cost .22 revolver, a compact pocket gun, or a factory optics-ready rimfire platform. The Model 617 Mountain Gun is for the buyer who wants a capable, well-finished revolver that will be carried, shot, and appreciated for decades.
