SARGE, you mention Jordan...I believe he coaxed S&W into the M19. It was his idea, the logic of being able to practice with low cost, easier on the gun, .38 Specials and load heavier .357s for duty....
The lighter than N Frame M19 was Jordan's idea of the perfect duty revolver.
Thats my reasoning for mid range reloads in my Rugers although I think the Security Six will probably take more magnum loads than the M19. FWIW, the Pa State Police (state troopers) adopted the 4" stainless Security Six with Pachmayr rubber grips before they switched to the Berretta 92 when LE went to high cap autos.
