The Bond Arms Cowboy Defender is a badazz little gun.
You can buy additional barrels to switch calibers.
The lowly .410 shell has received alot of upgrades since the Taurus Judge came into being. Remington makes a 2 1/2" HD round with 4 pellets.
Winchester PDX does theirs with discs and birdshot, essentially making little Rhodesian Jungle rounds. They sell it in combo packs with .45 longs.
Recoil is there, but I haven't found it to be unmanageable. It's frankly fun.
Primary carry? Maybe not. BUG? In my view, adequate.
Check their website, alot of good stuff there.
