I trust that the heavier made-for-the-FBI round is going to meet their penetration standards, and I've worked on so many cases in which adequacy of penetration has been an issue.
I am certain that S&W would not approve these +P+ rounds for use in their Airweight .38 Specials. As to what I do . . . well, I don't think I'll talk about that.
Everyone should be aware that I generally only use the rounds in question as back-up speedloader fodder for my .38s.
