The script called for Inspector "Dirty" Harry Callahan (Clint Eastwood) to use a Smith & Wesson Model 29 with a 4" barrel, chambered in .44 Magnum throughout the film as his sidearm. This proved troublesome for the filmakers, since the Model 29 was no longer in production at the time. Before shooting began, Clint Eastwood contacted Bob Sauer, then a representative for Smith & Wesson to aquire the gun for the film. It was a challenge, but Fred Miller at the plant had a couple assembled from parts eventually. To better familiarize himself with the weapon's handling and recoil, Clint Eastwood took one to a gun range and fired live rounds through it. Unlike the gun in the script, the only barrels aquired for the guns in this film were the 8 3/8" barrel and the 6 1/2" barrel. Both can be seen used in some scenes. The blanks it fired were custom made since the 5-in-1 blank didn't fit the chambers. It is said scriptwriter John Milius was presented with one of the actual guns used in the film as a gift later on.

Well, to tell the truth, in all this excitement, I've kinda lost track myself. But being as this is a .44 Magnum, the most powerful handgun in the world and would blow your head clean off, you better ask yourself one question: 'Do I feel lucky?' Well, do ya punk?" One should note that even in the 1970s, the Model 29 was not the most powerful handgun in the world, but he may just be fibbing about this to scare the punk more.Error creating thumbnail: File missingClose up of Callahan's Model 29.Error creating thumbnail: File missingCallahan shows the punk he had indeed fired six shots.
