Brass (and bullets) can be harder to buy for the .41, than the .44. If you go that route I'd acquire a lifetime supply of brass and maybe bullets. OTOH the best .44 bullets can also be spotty in availability.
I'd also scrutinize the barrel carefully; maybe go with an MGM or Bullberry over a TC barrel. Years ago I had a a scoped 10" .44 Contender, and my S&W 629 could shoot tighter 50 yard groups with iron sights, than the scoped Contender!
