Dirty Harry

Smith & Wesson Model 29

The script called for Detective Harry Callahan (Clint Eastwood) to use a Smith & Wesson Model 29, chambered in .44 Magnum throughout the film. The revolver used was said to be a Model 57 in .41 Magnum. (Scriptwriter John Milius was presented with one of the actual guns used in the film, and it is a Model 29 .44 Magnum.)

I remember hearing that the hero gun that was used for actual firing was chambered for .45 Long Colt as there were an abundant supply of blanks for westerns already at the studio armory.

S&W Model 29 - .44 magnum.
