The 19 is the K-frame. It was designed as a target gun for the 22/32/38 calibers, BUT the big complaint about the heavier N-Frame was the weight, so S&W included the 357 Mag into the k-Frame.

It is a good/bad thing. The guns are lighter, recoil needs more management and the guns will shoot themselves loose after a steady diet of magnum loads, Hence, the L-Frame was born, just for the 357.

Yup. Straight out of the box, the first batch of 158 grain SHP .357 through it managed to back out the ejector rod from the cylinder. After about the fourth speedloader, I couldn't open the cylinder anymore.

I mainly feed it a diet of semi-wadcutters, and load it with .38 +P for defense.
