I absolutely love my TRP 6" 10mm. I'm a big enough guy that I carry it daily. Open and concealed, either way. My Milt Sparks holster with an FBI cant makes it easy. Took it hunting this last fall hoping for a bear, but it didn't happen. Probably one of the sweetest shooting stock handguns I've ever had. Revolver or Semitauto. But then I changed the recoil spring, and it handled the heavy loads even better.
Never thought about a 10mm barrel on a TC. This idea intrigues me.
