The Ruger SP101 is a series of double-action revolvers produced by the American company Sturm, Ruger & Co. The SP101 is a small frame and all-steel-construction carry revolver, with a five-shot ( .38 Special, .357 Magnum, and 9×19mm Parabellum); six-shot ( .327 Federal Magnum, and .32 H&R Magnum); or eight-shot ( .22 LR) cylinder.
The Ruger SP101 was introduced in 1989 as the smaller-frame counterpart to the GP100. Together, these revolvers replaced Sturm, Ruger & Co's long-standing staple in the American firearms market, the Ruger Security-Six series revolvers. A 9 mm version was available until its discontinuation around 1998 but was later re-released in early 2018. A basic .22 LR version was also available until 2003 while a redesigned version was introduced in 2011. [3]
