i have always thought some of this was funny. I.E. a 38special 158grain doing about 850-900fps. Not good in some circles. a 9mm 147grain doing about the same velocity, wonderful. a 38 diameter .357 a 9mm diameter .355 yeah okay.
I always thought the 38 Special got a bad name from use in small snub revolvers, since that's what used to be "the thing" for concealed carry. That's not 850-900 fps, more like 650-700 fps if we're talking factory 158gr. A 9mm is generally a significant step up in that comparison.
