Like many mass produced products handguns in general and snub revolvers in particular are designed to be all things to all purchasers.  A little attention to specialization can go a long way to improving the personal protection snub. There are several gunsmithing services in particular that can enhance the self-defense snub. Four I consider particularly important include: Shrouded or spurless hammer, Double action only, Improved sights, and Chamfering the cylinder.
