Comparing 9 mm with .357 mag... no comparison (!) I heartily concur with ndolson............ Having shot full-pressure 9mm loads out of my fairly light Kel-Tec P11 and loads out of my 30 oz Rossi M677 6-shot 2" barrel .357 mag.......whew, no comparison there. While the 9 mm is brisk on recoil, the .357 mag is downright primitive. The violence of the blast noise, muzzle/gap flash, and recoil are practically off-scale compared to the 9 mm. When I'm firing the .357 mag in our local semi-darkened indoor shooting range with a bunch of other shooters, everyone seems to pause when the first couple of .357 shots ring out. It is a real attention grabber for sure.
