Ruger SP101

The Ruger SP101 is a series of double-action revolvers produced by the American company Sturm, Ruger. The SP101 is a small frame and all-steel construction carry revolver, with a 5-shot (.38 Special, .357 Magnum, and 9×19mm Parabellum), 6-shot (.327 Federal Magnum and .32 H&R Magnum), or 8-shot (.22 LR) cylinder.

History

The Ruger SP101 was introduced in 1989 as the smaller frame counterpart to the GP100. Both of these revolvers, together, replaced Sturm, Ruger & Co's long-standing staple in the American firearms market, the Ruger Security-Six series revolvers. While no longer manufactured, a 9mm version was available until around 1998. A basic .22 LR version was also available until 2003 while a redesigned version was introduced in 2011.^[2]
