Congrats on the Judge and welcome to the board. I like your "go big or go home" kinda attitude!
Far as the ammo (and feel free to correct me guys and gals) I think any 200gr 45 colt is considered a "low recoil" or "cowboy" round (as much as a 45 colt can be at least). I don't know of any "low recoil" .410s as they are already the smallest shotshell on the market. Hopefully someone else will have a little more info than me.
