The Ruger SR1911 is Sturm, Ruger & Co.'s first attempt at recreating the famed Colt 1911, introducing their own reputation for quality and reliability to the 1911. The SR1911 was Ruger's celebration of the 100th anniversary of the 1911, and another example of Ruger basing their firearm on a classic Colt (eg the Blackhawk whose design alluded to the classic Colt Peacemaker ).
