...the .38-44 load.... THEY DID NOT RECOMMEND THE K-FRAME Military & Police REVOLVER TO USE THIS AMMO.

Actually, at least in the late 40's... they did.
Honestly, I am dumbfounded that people still think that "+P" loads are like stuffing your cylinder with dynamite. The gun ain't gonna blow up. It's not gonna fall apart. It's not gonna wear out. People have been shooting Heavy Duty and "+P" factory and handloads for generations now in their K frames and even J frames.
S&W used an N frame to make their .38 Heavy Duty mainly because it was 1930. Even regular shooters were not used to any kind of real recoil. Most pistols simply didn't kick that much. The .45 acp was often considered a monstrous beast that kicked like a mule. People today may laugh at that, but at the time, heavy or sharp recoil was a problem. The N frame was chosen because it would be heavy, and reduce some of the recoil.
