Make sure you confirm with your gun manufacturer if your specific gun is rated for +P ammo.
There are several different cartridges for which SAAMI has established a second, higher pressure, +P version, including the .38 Special, 9mm Parabellum (aka 9mmP, or 9mm Luger), .38ACP, and .45ACP. You will note all of these are old rounds that were created before WWI, and because of that pressures have been held down due to older, weaker guns in these chamberings. Their modern counterparts are referred to as .38 Special +P, 9mm +P, .38 Super +P, and .45ACP +P.
What does a +P cartridge offer? Increased pressure means increased power in the form of higher velocity. Higher velocity means increased energy, or the ability to do work.
There are two downsides to a +P cartridge. It will have more recoil or kick than the standard version of the same cartridge when both are fired in the same gun. It will also be harder on the gun.
In .45ACP the difference in recoil between the standard round and the +P version really begins to be noticeable. Test fire some +P ammo and decide for yourself.
