I have a JM Marlin in 45 Colt and it's a workhorse -- eats anything from SWCs to heavy (340gr) flat points over full (full) loads of H110/296/V-N110 and smiles...
I picked up Rossi's better Italian cousin in a Chiappa `92 Winchester in 357 about six weeks ago that is beautifully-finished, had good ladder sights and as solid as a rock. It also eats pretty much anything over (full) loads of 110/296 and V-N110:
So I'd buy either one and be just as happy, and it would be a Spohie's choice to give up one or the other.
