Support Hand Only

I do this drill every week. It presupposes that my primary hand/arm is injured and cannot be used, so I draw from concealment using my support/left hand, reorient the pistol, press out and put 2 rounds on target.

It's good to be practiced at less-than-optimal techniques so that when you have to defend your life or the lives of others--and you're injured--it's not your first time to try and figure it out.
