It's a .38 Special revolver. +P applies to the cartridge, and indicates a more powerful load than a standard round of the calibre. In this case, it would be a .38 S&W Special with a +P loading, hence .38 Special +P.
You can fire regular .38 S&W Special cartridges through it. Whether or not it can fire +P or +P+ ammo, you need to read the instruction manual and find the manufacturer's information on this.
Depends on how old the revolver is.
A ".38 +P revolver" is simply a .38 Special revolver which is rated to fire +P loads. It's still a .38 Special, and the +P doesn't change the dimensions of the round itself.
yes, but not too often in a light weight 38 revolver.
It depends on how old it is. Needs to be examined by a gunsmith.
