My 1st question to this is : Am I going to be called out for sure, or am I going to be carrying my gun forever waiting for the faint possibility? Two completely different guns depending on the senerio. If I am just going to pack just in case, it would be a light .38 J frame. If it looked like a fight was a sure thing that I couldnt get out of, it would be a .44 special or a 45 colt. That is, if I didnt have a 1911. You know the 1917 was just about as fine of a fighting gun for a revolver ever designed! But in my case I would be happy with my .44 special 4" 24-3. Then again, I have a 3" model 66-3 from lew horton that I think a lot of too.
