Hard kicking and hard-hitting, the 10mm Auto cartridge is known both for its punishing recoil and impressive stopping power, especially when compared to .45 ACP. Not only does it fire a heavier bullet and produce more muzzle energy and stopping power but it also has a flatter trajectory, making it a solid “woods” pistol cartridge as well as a defensive option.
