The actual actors who demonstrated the fastest draw ability in real live. Jerry Lewis and Sammy Davis Jr. Davis could draw a gun at between 4/10ths and 4.5/10ths of a second. He also had very impressive gun twirling skills. Hugh O'Brian drew in 1/4 of a second. But reports state that Lewis and Davis were quicker. O'Brian challenged Audie Murphy but then declined when Murphy accepted but insisted on using live ammunition. Others who demonstrated fast draw abilities were Wally Cox, (The voice of Under Dog), Hugh Downs, Dancer Donald O'Connor, Singers Marty Robbins and Frankie Lane. Other fast draws you might expect were Glenn Ford, (Who had been timed at 4/10ths of a second), Clu Gulager, Clint Eastwood, Jock Mahoney and Ernest Borgnine. Jerry Lewis could also demonstrate very good gun twirling skills.
Other gun enthusiast were Merv Griffith who was a competitive trap shooter, and would routinely practice on his terrace behind his Hollywood Hills home, much to the dislike of his neighbors, and Lon Chaney and Chaney Jr..
None of them were as fast as Bob Munden but he was a freak of nature.
