Harry Callahan, played by Clint Eastwood, made the Model 29 in .44 Mag. famous while challenging his nemeses in the “Dirty Harry” movies. At the time, the .44 Mag. was considered the big boy on the block, though today, it has been eclipsed by the .454 Casull, the .460 S&W and the .500 S&W. However, there is still just something about holding a Smith & Wesson Model 29 in .44 that makes you want to dare: “Go ahead, make my day.”
