What is your theory, then, about why S&W originally introduced the 357 Magnum on the N frame and didn't introduce it in the K frame until as late as 1955?
How does that put back that argument? Like I said, the 9mm was always running at the pressure it runs at today. The guns of that era were designed to run on that pressure. It's so tiny it has to make pressure to run the gun.
Do you think a 1920 Colt Police Positive could handle full power Keith 38 loads or 357 Magnum loads if someone reamed out the chambers?
Hell, even further...why do you think S&W even bothered making a brand new cartridge, the 357 Magnum, and making it longer so that it wouldn't chamber in anything but new guns made in 357 Magnum? Doesn't that seem like a lot of expense and effort if the old guns could handle its pressures? Surely they would have made a boatload more money if their new caliber was backward compatible with the (millions?) of 38 revolvers that already existed by 1935?
