I got a Ruger Blackhawk .357 mag. convertible with a spare cylinder in 9mm. I have had this pistol in my safe for years and have only fired one cylinder of 9mm rounds thru it in all this time. I dont think I have ever fired .38 special thru the .357 cylinder. what are the ballistic differences in 9mm rounds thru the .357 mag compared thru a 9mm chambered pistol. I know there are not too many 9mm revolvers out there.
