Not to further derail the thread....but this is the reason why I consider a double action to be almost a requirement for a backup gun. I want something that I am able to unholster and fire with a minimum of gyrations required. While cocking a single action may be second nature, if you are actively trying to keep a bear off of you with one hand, the hammer cocking action may be a bigger hurtle than is surmountable, pulling the trigger might be as well but I would like that as an option.

This is another good reason why short barrels are preferred. The 7 1/2" SBH can be unwieldy when trying to work it around close to your body.
