The Ruger Single-Nine in .22 WMR gets good marks from shooters who want a larger-capacity rimfire revolver with practical sights.

Build quality and finish come up first. The satin stainless holds up well, and Ruger's fit and finish on this model consistently earns compliments. The nine-round cylinder is a genuine differentiator in the single-action rimfire segment. Most users appreciate more rounds before reloading, especially for range sessions or small game hunting. The Williams fiber optic sights are well regarded for practical use, performing better than standard blade sights in variable lighting. The .22 WMR caliber is considered effective for small game.

The single-action mechanism draws some comment. It's the expected character of the platform, but buyers new to revolvers occasionally note the manual cocking requirement affects pace. Weight at 39 oz. is heavier than some expect for a rimfire, which comes up occasionally in carry or hiking contexts. The hardwood grip gets mixed feedback on ergonomics for faster shooting cadences. Aftermarket accessory options are narrower than for larger-caliber platforms.
