S&W or Ruger. Must have a 3" or longer barrel. And for all you nay sayers miracles do happen. There was a 547 for sale on another forum for $500. It went in 3 minutes. Surprised it lasted that long.
Pretty sure he means that the listed shops can convert a 357 gun to 9mm, up to 9x25. Only issue is the bore is slightly bigger on a 357, vs 9mm's .355 bullet diameter.
They made it in both lengths. I've been offered the snubby version but I want a minimum of 3". They also made a speed six in 9mm but so far have only found it in snubby too.
