You are correct, the
P in
+P does stand for the word
Pressure
Everything else being equal, more pressure will give you more velocity
The SAAMI
+P designation indicates that this round of ammunition is loaded above industry standards
So if you have two identical rounds from the same manufacturer one being standard pressure and one being
+P, the
+P round will always leave the handgun barrel faster than the standard pressure round.
It does not matter what handgun we are talking about
The question should be, is the gain received worth the extra wear and tear that a
+P round imparts on the firearm over a standard pressure round of ammunition
In my teeny, tiny polymer framed 9MM pocket pistol, I always carry standard pressure ammunition. If I am carrying a slightly large metal framed pocket or personal pistol I will usually carry the
+P offering
