Ruger, SR22 3604, 22 Long Rifle, 3.5 inch, 10+1, Satin Stainless Threaded Barrel

The Ruger 3604 SR22 is a compact, shooter-focused 22 LR pistol in the SR series that combines a 3.50" stainless 1/2"-28 threaded barrel with a satin finish and a black anodized serrated aerospace-grade aluminum slide for reliable target acquisition and easy slide manipulation; the threaded barrel accepts common 1/2"-28 muzzle devices and ships with a barrel cap adapter and wrench, making it ideal for suppressed-range work, rimfire training, and recreational plinking. With a 10+1 capacity, light double-action and crisp single-action trigger pulls and an external hammer with a rounded spur, this DA/SA pistol offers controllable follow-up shots and straightforward single-action shooting for marksmen transitioning from centerfire autos. The black polymer frame with Picatinny-style underside rail handles lights or compact optics adapters, while two interchangeable rubberized grips allow shooters to select a slim or wider palm swell without tools for better ergonomics across hand sizes. The dovetailed, high-visibility three-dot sight system features a fixed front and an adjustable rear with a reversible blade for two sighting options, and ambidextrous manual thumb safety/decocking levers plus an ambidextrous magazine release, visual inspection port, simple field-stripping, soft case, and a sub-18 oz feel (17.5 oz) round out a versatile, range- and training-ready semi-auto that requires FFL transfer.
