How about a Uberti 1873 replica in .357 and a .357 Vaquero? Both are short-stroked and tricked out. The newer Marlin quality is not as good as before Remington took over, though they can be made to run. Hard to beat a Ruger for durability and combined, these guns generally rule the CAS shooting matches.
Come to think of it, I don't think Marlin has a movie named after it like the one Jimmy Stewart starred in.
