The All-American 2000 was Colt’s attempt to compete with Glock for the military and police service pistol market. It had a polymer frame (except a few early ones with aluminum frames), a double-action-only striker firing system, double-stack magazines, and used a rotating barrel to lock. The design was originally the brainchild of C. Reed Knight and Eugene Stoner, and the production rights were sold to Colt. The Stoner/Knight prototypes worked well, but Colt made some design changes and did a poor job adapting it to mass production. The result was a huge commercial flop, as the guns were beset by accuracy and reliability problems (despite a massive whitewashing by print gun magazines at the time).
I will have a full video on the All-American in a few weeks, but figured the rotating-barrel slow motion deserved its own post and video:
