Since you've been shooting 9mm, I'll put it to you in these terms, 38+P out of a 2" barrel is very close in ballistics to standard pressure 9mm. Standard 38 is just a .... hair better than a 380.
I carry +P in my J-frame, I feel that the added velocity aids in reliable expansion. I also use (almost extensively) anything with the XTP bullet.
This is just one man's opinion and should be taken such.
