Ruger GP100
The GP100 is a family/line of six-shot double action .357 Magnum/.327 Federal Magnum revolvers made by Sturm, Ruger & Co., manufactured in the United States. It was introduced in 1985 as a second-generation of the Ruger double action, exposed hammer revolvers intended to replace Ruger's Security / Service / Speed Six line. It was made stronger with the intent to fire an unlimited number of full-power .357 Magnum rounds and has been produced in a number of variations with three basic barrel lengths (3" / 76 mm, 4" / 102 mm, and 6" / 152 mm), various barrel profiles (full lug and half lug), fixed or adjustable sights, and in blued carbon steel or polished stainless steel.
