I think that the max pressure for .38 spl is 17,000 psi. The pressure for +P .38 spl is 20,000 psi. That's not exactly a scream of difference. My Speer manual states the velocity for a 158gr lswc is around 800 fps vs. 900 fps for the +P give or take depending on powder.

I shoot both in my M15-4. I have found no difference in accuracy between the two, but the +P makes a bit more noise.
