Analysis

This .22 LR revolver offers a solid option for shooters seeking a reliable rimfire handgun. Its accuracy is commendable, particularly for target practice and small game hunting, thanks to a well-aligned barrel and consistent cylinder lockup. The ergonomics are user-friendly, with a grip that fits most hand sizes comfortably, promoting extended shooting sessions without fatigue. Reliability is a strong point, as it cycles smoothly with minimal malfunctions when properly maintained. The trigger pull is crisp, averaging around 4-5 pounds in single action, though double-action pulls are noticeably heavier. Felt recoil is negligible, making it ideal for beginners or recoil-sensitive shooters. On the downside, maintenance can be cumbersome due to its design, requiring diligent cleaning to prevent buildup. Parts availability may pose challenges for repairs, and some users might find the weight slightly cumbersome for concealed carry or prolonged field use.

High Standard Sentinel .22 cal

I have one of these I bought used a couple of years ago. After trying it for function, it is now part of my collection. It worked fine. Other than the aluminum frame, it is well made and was cheap to buy.
