I know this has been done to death in other threads and it has just been touched on in the multiple styles thread. Plus I was just now watching "Best Defense" Concealed Carry Gone Wrong.

Close Quarter empty-hand skills are a part self defense even with a sidearm on hand. So are MA skills out of date in a gun culture like the US?

Obviously not, but does MMA type training fit the bill?

I really don't think so. For the guys that carry have you looked at your CMA with an eye towards covering yourself until you can draw your firearm safely and fire if needed?
