Ive got a Ruger Blackhawk .357 mag/9mm convertible with 7.5" barrel I used for hog hunting for years. I realize that barrel length doesn't make it a practical self defense gun, I got other pistols for that. I have never fired 9mm through it. Just wondering what accuracy with a 9mm is out of a barrel that long and what is the basic difference in diameter. I don't have 9mm, I am a .45 acp person.
