Parting Shots: 45 Long Colt vs. 44 Magnum

The 45 Long Colt and 44 Magnum both have their own unique appeal. The iconic Colt Single Action Army revolver was chambered in 45 Colt (though it initially used black powder instead of modern propellant), while Dirty Harry made everyone who didn't already own a 44 Magnum jealous.

Whether you're using a lever-action rifle or revolver, the 44 Mag is more powerful and better suited for hunting. Even so, many other handgun cartridges have been developed that better suit the needs of shooters since the creations of the 45 Colt and 44 Mag.
