Notes
The .22 LR SP101 (model 5765, catalog KSP-242-8) holds eight rounds versus the five-round capacity of the centerfire SP101 models. It shares the SP101's transfer-bar safety and triple-locking cylinder.
Background
Ruger first introduced the SP101 as a small-frame centerfire defensive revolver in 1989. The eight-shot .22 LR version, added in 2011, gave the rugged platform a low-cost, low-recoil trainer that mirrors the handling of its .38 Special and .357 Magnum siblings.
