In short barrels there is a school of thought that says the .357 merely generates more muzzle flash than a .38spl. Not much performance can be expected from a 2" Barrel. From 4" and up the difference is major.
I have a 38spl with 2" barrel that's nice to carry when looking for a good reliable "pocket gun" and it's loaded with 130gr GDHP Short Barrel ammo. This ammo is designed for reliable expansion at the low speeds common from shorter barrels. A good combination for real close quarters Defense and backup although for backup I prefer my P3-AT. Fits a pocket better, even a shirt pocket.
