In the second Dirty Harry movie, Magnum Force, Lt. Briggs pulls a revolver on Callahan in the car after the mailbox bomb is unsuccessful. What type of S&W is it? It is larger than a J frame but still looks to be a 2" barrel, maybe a 2.5 inch? Does anyone know if it is an L or N frame? I know at the end Briggs has a 4" Python but in the car he pulls out what is clearly a S&W. I'm 99% sure anyway, I have not watched the movie in a couple of weeks so I might be mistaken but this is something that sticks in my head.
