The Ruger SR22 is most often talked about as a training and plinking pistol, and in that role it performs well.

The interchangeable backstraps get frequent praise. It's a genuinely useful feature that lets the gun fit different hand sizes. Reliability with quality .22 LR ammunition is consistently positive, though like most rimfire pistols it can be picky about bulk or low-velocity rounds. Accuracy at typical .22 distances is good; most shooters report easy, consistent groups.

The compact size and low weight at 17.5 oz make it a practical carry option or backpacking companion. The ambidextrous safety and slide release are often noted as user-friendly features, especially for new shooters.

A few users feel some components feel less robust compared to centerfire pistols at a similar price, though it holds up well for .22 use. Value for money is consistently rated as good.
