Ammunition loaded to higher than normal pressure.
Yes, you can shoot .38 P (plus-P) cartridges in a .38 Special revolver, provided the firearm is rated for plus-P ammunition. Plus-P loads generate higher pressure than standard .38 Special rounds, offering increased performance. However, not all .38 Special firearms are designed to handle this increased pressure, so it's essential to check the manufacturer's specifications before using plus-P ammunition.
Simply put, ammunition that is loaded to a higher pressure to achieve more velocity.
If you mean +P, the difference is velocity.
A pistol rated to fire .38 +P ammunition is still going to be a .38 Special pistol, and can use regular .38 Special ammunition. .357 Magnum revolvers are also capable of chambering and firing .38 Special loads - regular, +P, and +P+ included.
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.
you can shoot standard 38 special rounds out of a firearm marked for 38 special +p
You can use 38 special.
Yes it can. I do not think you will exceed the .357 pressures with .38 +P.
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.
