I've always been a revolver guy. I keep a stable of snubby revolvers which I can and do carry. Typically an LCR-357, SP101, S&W 60, 638, or 642.
For concealed carry, alone, I favor the LCR for its lighter weight, and low cost. I also find some comfort in carrying an ugly polymer revolver revolver, as it won't break my heart watching it get battered with age, nor if it's ever confiscated and "lost" in an evidence locker. It wouldn't necessarily break my heart losing the others either, as I came to grips with those realities long ago, but I care less about the LCR than I do the others.
But... Of course, a carry piece is fired for practice far more than it would be for it's intended application, so it's a natural (albeit naive) compulsion to have our carry pieces be friendly on the range too. In that case, I favor the 638 over most of these other models, as it offers the snag-proof advantages of an internal hammer, but with the retained ability to be fired DA and SA, as opposed to DAO.
Give me an ultralight 357mag shrouded hammer for $450, I'm all in.
