I'm about to change from a Glock 19 to a Glock 23 for EDC. I know 9mm is a respectable round, but I've been watching a lot of videos about .40 cal and it's obvious it has more stopping power. I'm a pretty decent shot at 15 yards or less, but that's at the range. My logic is, if I'm ever in a self defense situation and shooting under duress, .40 cal would at least give me the advantage of better stopping power if I'm not as accurate. Am I right or wrong?
