Trivia
Dirty Harry's .44 Magnum was not the most powerful handgun in the world at the time. In fact, among firearms enthusiasts (such as screenwriter John Milius, an NRA Board Member), there were a few relatively-well-known examples of pistols that were more powerful. Perhaps best-known was that R.B. Rhodda & Co. of Calcutta had sold a number of side-by-side pistols in .303 British during the 1890's through the 1920's. The .303 is a relatively potent rifle caliber that is significantly more powerful than the .44 Magnum. With that said, I can certainly understand why an SFPD officer wouldn't be lugging around an unwieldy, side-by-side, two-shot pistol. See more...
