Unique or 2400 will do you just fine. I like 21 grains of 2400 with a plain base 245 grain RCBS cast bullet, 22 grains of H110 with the same bullet, or 21 grains with a 310 grain gas checked Lee bullet. The recoil isn't a problem to me, and is doesn't get cold enough here for me to need a magnum primer, altho I do have some and occasionally will use them.
I do so hope you're savvy enough not to be firing that handgun without ear protection. The sound will cause irreparable damage to your hearing and will also be conducive to a flinch that won't be easy to get rid of.
As said before, be cautious and follow the loading manual's instructions when using H110, it's not a powder that should be loaded down. It's made for full powered loads. Try some Blue Dot or Herco , Unique or something else if you need lighter loads, and work yourself up to the "stout" loads. It's not a good idea to attempt to be Mr. Macho when you're learning a large caliber pistol or revolver.
