+P has more muzzle velocity
If you mean +P, the difference is velocity.
Call S&W and they will tell you when it left the factory. 100-300 USD
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.
There is no such thing as a ".38 Special +P" firearm - it's still a .38 Special, with some indication from the manufacturer that it is capable of handling the higher chamber pressures of the more heavily loaded +P cartridges. That's the only difference between a regular and a +P cartridge - more powder.
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.
NO, NO, NO, NO, NO, NO, NO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! DO NOT EVEN TRY TO DO THIS!!!!!!!!!!!!!!
Only if made from 1997 onward.
you can shoot standard 38 special rounds out of a firearm marked for 38 special +p
I have that same pistol and want to know where to get bullets for it ! .38 S&W special is the same as .38 special. Just avoid cartridges marked +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.
The only serial numbers that are that high in range were assigned to the 38 special Hand Ejector Military and Police(M&P) that were made between 1940-1945.
