Smith & Wesson Model 29 in .44 Magnum
"I know what you're thinking. 'Did he fire six shots or only five?' 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?"
Remington Model 70 in .458 Winchester Magnum
Auto Mag Corp Model .44 Auto Mag
From the fourth Dirty Harry movie, "Sudden Impact," the .44 Auto Mag pistol is a large caliber semi-automatic pistol produced from 1971-1982. The short-recoil operated Auto Mag pistol featured a rotary bolt with six locking lugs located at the front similar to the M16/AR-15 rifle. The .44 Auto Mag was designed to shoot .429-inch, 240-grain bullets with comparable velocity to the .44 Magnum revolver, which is probably why it appealed to Dirty Harry Callahan.
