I'm a fan of the 9mm, but it's not up to .357 standards. Velocity and muzzle energy are only part of the equation. Bullet weight, composition, and shape also make a significant difference.
This is absolutely correct. Quite simply, the types of bullets which can be used without issues in a revolver would choke many, if not most, semi-automatics. While one can find loadings in 9mm +P/+P+ and .357 Sig that come close to, or even meet, the .357 Magnum's paper ballistics, they do not use the semi-jacketed hollowpoint bullets that gave the .357 Magnum its fearsome reputation for effectiveness.
