About this product
The Chipmunk Hunter Pistol, item number 41105, is a single-shot, bolt-action pistol from Keystone Sporting Arms chambered in .22 WMR (.22 Magnum) with a 10.5-inch threaded barrel and a camo laminate stock. Keystone is best known for the original Chipmunk youth rifle, and the Hunter Pistol applies that same simple, rugged single-shot design to a pistol format built for small-game hunting and pest control.
How does a single-shot bolt-action pistol work?
Unlike a semi-auto or revolver handgun, the Chipmunk Hunter Pistol is manually cocked before each shot: the shooter loads a single round, closes and cocks the bolt, and fires — there's no magazine and no automatic cycling between shots. That simplicity is part of the design's appeal for hunting and pest-control use, where a single well-placed .22 WMR round is typically all that's needed, and the manually-cocked action adds a deliberate extra safety step compared to a pistol that's ready to fire the moment a round is chambered.
What are the full specs?
This pistol runs a 10.5-inch barrel with a stainless finish, threaded at 1/2x28 with a protective thread cap included for when a suppressor or muzzle device isn't installed. The trigger pull is rated at 2.5 to 3 pounds, and the pistol weighs approximately 2.5 pounds. It uses a right-hand bolt design on a left-hand-oriented receiver layout, fiber optic sights for quick target acquisition, and this listing's camo laminate stock for a distinct look and some visual concealment in the field compared to a plain wood or synthetic stock.
Who is the Chipmunk Hunter Pistol built for?
This pistol suits small-game hunters and pest-control shooters who want a lightweight, simple, single-shot .22 WMR platform, along with plinkers who appreciate the deliberate, manually-cocked shooting experience over a semi-auto rimfire. The threaded barrel makes it a candidate for a rimfire suppressor where legal, which pairs naturally with pest control use where a quieter report is often preferred. It's not intended as a defensive handgun given its single-shot capacity and manually-cocked action.
Because this is a firearm, it cannot ship to your home address. It transfers to a licensed FFL dealer near you, where you will complete a background check and the required paperwork in person before taking possession. California maintains its own certified handgun roster; buyers should confirm current roster status for this specific model with their FFL before ordering, since single-shot pistols can sometimes fall outside standard roster requirements but this should always be verified for your specific situation.
The .22 WMR chambering gives this pistol noticeably more energy downrange than a standard .22 LR pistol, making it a more capable choice for small-game hunting at slightly longer ranges while still keeping recoil and ammunition cost well below any centerfire handgun cartridge. Because the design is manually cocked for every shot, it also tends to appeal to shooters who want to teach deliberate, single-shot marksmanship fundamentals rather than rapid-fire practice, making it a reasonable choice for introducing a new shooter to handgun fundamentals in a controlled, methodical way.
The camo laminate stock on this configuration also holds up well to field conditions compared to a plain wood stock, since laminate construction resists warping and moisture absorption better over years of outdoor use — a practical consideration for a pistol that's likely to spend real time outside during hunting or pest-control trips rather than staying in a range bag.
