We all hope we can always have the opportunity to use both hands, all our brain, 20/20 vision, full daylight, cat-quick reflexes & Doug Koenig's shooting form when a Self-Defense situation presents itself. Sorry to tell ya', it's NOT gonna' be that way. Murphy WILL BE in attendance. We'll be surprised, shocked, confused, heart-pounding, mind-racing, tangled in our seatbelt, scared "witless", struggling to see, processing info, looking for cover, carrying precious cargo, while we twist our ankle. Practice shooting "skills" in ideal conditions with both hands & a trained, consistant grip. Practice "practical" shooting with one hand (both left & right) from every possible position & condition. Because you can't call time-out in a gunfight.
