Also many have stated that folks increase caliber to make up for lack of ability or tactics. I believe that puny primary caliber carriers push forth this notion to justify carrying puny and while it may be true for a sizable part of the gun carrying world, I believe it is not true for most of the folks here on TFL nor does it increase punys punch. Most of us have given much thought to our self preservation and I would speculate even more so those of us in this debate on both sides. Most of us train on both sides. Most of us have developed tactics that fit our needs.
So when you feel the need to tout training just remember the bigger is better crowd trains also. All the training in the world won't make puny penetrate better.
