I like SBs for duty weapons. The SB seems to have been so ppular that it is all S&W makes. The Js still have RBs. The grips are so oversized, it is hard to tell. I prefer RB for target shooting. It moulds into my grip well. If it were up to me, S&W would make 32 H&R Magnum, RB, 5", 4 Ts revolvers. It isn't and they don't. They should.
