Handguns, the gun you have with you when you can't carry the .50 BMG or the .375 H&H rifles with you lol. What is your favorite handgun cartridge(s)? .38 Special and .45 ACP take the top for me. I'm a bit of an old soul at heart so I love the classics. Note: Please exclude rifle cartridges like 45-70, 30-30 or any other that the BFR is chambered in. After all, they're still rifle cartridges, just in a handgun.
