There are several companies marketing revolvers chambered for .410 shotshells &/or .45 handgun rounds, and with the dozens of different .410 loads -- slugs to birdshot to slug-shot combinations, or mixed .45s and shotshells -- you can tailor your rounds to your own particular needs.
These are big revolvers, though, not easily concealed. A stacked derringer might be more practical, with maybe BB shot in the top barrel and a .45 or a Winchester PDX1 as backup, in case an assailant doesn't get the message.
.... or he has a friend.
I like to have at least four shots.
