The lightweight Ruger® SR1911® in .45 Auto. This model gives you the feel and accuracy of a full-sized SR1911, but its aluminum frame makes the pistol nearly a 1/2 pound lighter (7.9 oz) than classic stainless steel frame SR1911 pistols.
Great pistol, took it straight from my FFL to the range...100 rds later perfectly happy. Now I need to reload some 45 ACP to feed it.
