I suspect you are correct, that it'll take the S&W cases, but, If you happen to get the gun & find it's chambered for the smaller diameter 32 Colt, I have a box of both short & long "Colt" cases, ( I think the long cases are even primed ), that are in my gun show box, that didn't sell at the once a year gun show I sell at... just in case you'd need them
