Thought I might start a S&W thread since I don't see one. My thoughts are mainly for revolvers, but semiauto posts won't be shunned by me . I'll start with one of my personal faves, my 4" model 57 no dash in 41 Mag. Great cartridge IMO, and as a reloader its really no more costly than other revolver rounds. This one is also a "3T" gun, having target grips/target hammer/target trigger.
