Ruger 3620 SR22 22 LR 4.5in 10+1 Satin Stainless Aluminum Slide Polymer Frame

The Ruger 3620 SR22 is a member of Ruger's SR22 line that brings a shooter-friendly .22 LR semi-auto in a lightweight 18.7 oz platform with a 4.50" satin stainless barrel and a serrated aerospace-grade black anodized aluminum slide for easy manipulation; its DA/SA action with a light double-action and crisp single-action trigger and a rounded external hammer makes it ideal for training new shooters, dry-fire practice, range sessions, and small-game outings. The black polymer frame with Picatinny-style underside rail accepts lights and lasers, while interchangeable no-tools rubberized backstrap grips let you switch between slim or wider palm swells for consistent control; ambidextrous manual thumb safety/decocker, ambidextrous magazine release, and a visual inspection port support safe handling and clear chamber checks. The dovetailed high-visibility three-dot sight system offers a fixed front and windage/elevation adjustable rear with a reversible blade for two sighting options, and the stainless replaceable barrel, 1:16" RH twist, six grooves and easy field-strip design make maintenance and ammo testing straightforward. With a compact 7.40" overall length, 0.97" width and MA-approved certification, the SR22 combines rimfire economy with full-size ergonomics for shooters who value accuracy, controllability, and dependable function; requires FFL transfer.
