There's no getting around the fact that you will lose muzzle velocity in a 2" snubnose revolver compared to longer barrel lengths (ie 4-6"). But a +P cartridge will start out at a higher velocity compared to the same weight bullet in a standard pressure loading, so it's certainly not "useless."
Fact is, carrying a snubnose necessarily incurs a compromise in terms of muzzle velocity - you're trading a certain degree of potential lethality at longer ranges for a more compact and lightweight package. Given the intended ranges at which snubbies are intended to be used, it's a worthy compromise for a lot of folks.
