DO NOT STUFF A .32 ACP IN THAT THING!!!
Otherwise, monkeys at the zoo will taunt you for your lack of an opposable thumb!
There was a European .320 Revolver cartridge, which happens to be the same as a .32 Short Colt. NOT a .32 S&W.
Have a smith check it over- but I would not shoot it with anything. Rossi has gotten better at quality, but made some REALLY punk stuff in the early days, suitable for very low power black powder type pressures. Would be a great gun to put in a shadow box with a Royal Flush- after removing firing pin.
What we have here is... failure- to communicate.
