If your thinking 10mm in a revolver take it to the next level and go to 41 magnum. With some hunting you could find astainless redhawk factory chambered in 41 have it chopped to whatever length you want and still be spending way less then a custom 10mm. With what your going to lose between barrel length and cylinder gap your going to probable be down near 40 s+w instead of true 10mm ballistics. Only real advantage with the revolver is no possible feeding issues.
Exactly why a 10mm over a 41 mag in a revolver. The 10's appeal is in a semi auto IMHO
