I am looking at a Taurus model 85 with 2" bbl in .38 special (ultra light). I want it for backpacking and concealed carry. I started out thinking I wanted a .357. The little 85 is rated for +P. What kind of performance differences can I expect from a .38 +P round vs. an average .357 round? I am thinking about getting a crimson trace laser grip with it for a little easier pointability on such a short gun.

One other question, is there load data for reloading +P rounds for the .38?
