History

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.
