I know that .38 and .38 +P (and .357 Mag for that matter) all perform better when shot out of a longer barrel. I'm wondering if +P makes enough difference when shot out of a 2" snub to be worthwhile? It sure couldn't hurt, so I carry it. But I'm wondering if I'm wasting my time. Most of the ballistics charts I see don't specify the barrel length and I assume they mean full-sized. BBTI unfortunately doesn't list +P.
