OH YEAH !!!
Your gonna DIG that pistol..! Some really good rounds for self defense are actually made for the lever action rifles, they have a soft red pointed tip (so the round ahead of it doesn't have the primer go off in the tube) and have really good penetration and expansion. I Think it's called Leverevolution..? and is made by Hornady, Its a 140 grain flex tip ammo. Midway has it, but you just have to type in "leverevolution" in the search box on the home page. There are also trijicon night sights or their alternatives, like meppro. Oh almost forgot speed loaders, practice with them, the sppedloaders also have their own holsters as well. There are also some back packs that make great range bags too, Have fun and be safe.
You'll run out of ammo quick..!
