OK, in the 'other' (a.k.a.: just because it's cool) category, get a .357 single action of your choice to go with your rifle. They're fun to shoot, relatively easy to clean, and keep you from burning thru your ammo quite as fast as you might with a double action rev. or with a semi-auto. Barrel length and finish (stainless, nickel, blued, casehardened) at your option. I'd recommend against any barrel length over 7.5". They're fun at first, but the inconvenience of holstering or carrying sets in, and they begin to feel like field artillery when aiming.
I'm partial to Ruger SA's as they're a good value, built like tanks, and the transfer bar mechanism let's you load all 6 chambers without concern. With the popularity of S.A.S.S./Cowboy action shooting, there are a lot of good alternatives out there, from a variety of manufacturers. Enjoy!
