John Browning developed the .45 ACP in the early 1900s, and it was adopted with the M1911 pistol. Standard 230-grain loads are subsonic, which makes the .45 naturally quiet with a suppressor.
Recoil is more of a push than a snap, but capacity is lower than 9mm in the same size gun, and ammunition costs more.
Modern defensive loads perform well, and many shooters simply love shooting a .45. It remains a strong choice for home defense and 1911 fans.
Always use only the ammunition marked on your firearm’s barrel or slide, and follow the manufacturer’s guidance.
