To this day, I still have people come into my gun store and every large revolver in stock, someone will reference the movie Dirty Harry. This movie and Mr Eastwood made the Smith and Wesson model 29 44 magnum one of the most sought after revolvers in history. This baby had a MSRP of $194 and they were flying out the door at $600 or more if you could even find one in the early 70’s. When you do a little research you find that this cannon was not a big seller before the film so variety was a little scarce. John Milius, who wrote the first two films, was seeking a 4-inch nickle plated with ivory grips for the fictional cop. As the story goes, when they requested the firearm, Kelly Lookabaugh who was S&W’s west coast representative brought the 6 1/2 inch blued model and since the studio also needed a backup for filming they went with that version.
