In a brief discussion with Larry Houck at last year's pandemic shoot, we discussed this topic. Being of a law enforcement background, another shooter presented this question to him and his response was that anything which makes you fast and accurate has zero disadvantages, so long as you train/practice in both disciplines and treat them as separate, yet complimentary. I couldn't agree more. I struggle to understand how this is such a contested topic? Things encountered in competition like fast target identification/acquisition, transitions, strong hand/weak hand, barriers, etc. are all skills that are beneficial if you're getting shot at or not. Not to mention the addition of a degree of stress.
