Thanks for the advice guys! I'm thinking I'm gonna go with the Crossbreed. It seems like it would spread the weight of the gun out pretty well. Got to take the 21 to the range yesterday and it shoots like a dream. Not a single issue with the WWB ammo, Ranger T's (my carry round), or with any of my reloads, it shot them all just fine.
Violence is seldom the answer, but when it is the answer it is the only answer
