The cases were originally loaded with higher pressure, higher velocity loads for the 38 Special revolvers. Not to be used in older revolvers chambered for the .38 Special cartridge.
+P has more muzzle 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.
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.
If you mean +P, the difference is velocity.
you can shoot standard 38 special rounds out of a firearm marked for 38 special +p
The .38 Smith & Wesson cartridge was created in 1876. It is a shorter, fatter, less powerful cartridge than the .38 Smith & Wesson Special, created in 1899 (they cannot be interchanged). The .38 Special +P is a .38 Special cartridge that is loaded to 10% higher energy than a standard .38 Special. The .357 Magnum is a longer version of the .38 Special that is loaded to MUCH higher energy than a .38 Special +P.
You can, but, you should not. The frame is not rated for +P
.38 special Stay away from the "+P" ammo
Depends on the pistol. If there's nothing about this in the owner's manual, or there is no owner's manual, you should contact the manufacturer for clarification on this matter. If you're unable to do this, a gunsmith should be able to determine this for you. .38 Special +P is .38 Special ammo, but with a higher powder content, which generates higher chamber pressures. Older .38 Special revolvers which were manufactured before the advent of the .38 Special +P cartridge did not have to be mindful of this when they manufactured their revolvers.
Yes it can. I do not think you will exceed the .357 pressures with .38 +P.
You can use 38 special.
