The exposed hammer.

There is simply no realistic or practical need to retain single action capability on a modern day personal defense revolver. Not only does the external hammer come with the potential for inadvertently cocking it in a high stress situation, but it can cause snagging issues during the draw(especially with pocket carry), it cannot effectively be fired from inside the pocket(or purse), the hammer can be obstructed or get entangled in clothing during a close-quarter struggle or an assailant grabbing your weapon in a disarm attempt. I think the enclosed hammer "centennial" models are much more suitable for concealed carry.
