44 vs 45: When Muzzle Energy Matters
The 45 Automatic Colt Pistol (ACP) and 44 Magnum are two powerful handgun rounds that are rarely compared. Although the bullet that each cartridge fires is separated by only a few hundredths of an inch, the terminal ballistics of the 45 ACP and 44 Mag are considerably different from one another.
This leads some new (and experienced) shooters to question if they need a higher pressure 44 Magnum revolver for self-defense or if the 45 ACP has enough stopping power to do the job.
In this article, we will compare the 44 Magnum vs 45 ACP to help you understand the difference nuances between two of the handgun cartridges that are synonymous with home defense, firepower, and freedom.
