Name the film: "Go ahead, make my day"

Classic Nerd
Clint Eastwood had this weird talent for making the most ridiculous threats sound genuinely terrifying. Picture a guy eternally in his 50s squinting at criminals and basically daring them to give him an excuse to shoot, and somehow it worked every single time. One particular line got so famous that Ronald Reagan started using it in actual presidential speeches. Which movie gave us "Go ahead, make my day"?
