Gentlemen,
I worked in Cleveland's worst area for over 13 years with a model 10 heavy barrel. I felt 'undergunned' only one time (the only time on the job that I was really worried.) The revolver will do 98% of what you have to do, providing you do your part.
I love them - and always will. To this day (retired 11 years) I carry a 2" model 60 from 1974.
Semper fi,

Dave Swaffield
