It appears from my research and reading here, plus watching you tube videos of actual crimes and CCW, the following can be surmised: Most acts of crime are very quick, thus giving you very little time to react. Therefore it makes sense to have a round in the chamber plus very easy access to the gun. I don't have a problem with the round in the chamber theory, however, I am required by work to tuck in my dress shirt and slacks. How do y'all deal with that? Also, from watching the videos, usually only 2-3 shots are fired either way. A shoot out with 10+ shots seem rare unless you are a LEO in the line of duty. What I'm saying is person to person, rarely would you have a shootout. Therefore, it makes sense to have the most stopping power in those 3 shots, vs. 10+ rounds of something less potent. So my impression is a .45acp with a single stack should be sufficient in most CCW situations. Am I on the right track? Obviously these are just an opinion, and your response will be welcome.
