There was a test question in the current Guns&Ammo re what such guns were called in the olde West.
Correct answer was Mormon Avenger.
Appearently they were carried by Orrin Parker Rockwell, early church member, body guard, deputy Marshall, etc.
The Wikipedia entry for his name is interesting.
Got to go to a Preisthood meeting right now so later....
looks nice so far!
