There is a strong demand for rap “music” in the entertainment industry too. Doesn’t mean it’s any damn good.
Although I have settled on carrying 9mm, I actually agree that .45 is probably more effective.....if you hit your target. I’m reasonably confident that I can hit a target most of the time with either caliber. And like many, I find the .45 reasonably easy to shoot......certainly no more difficult than shooting 9mm. The only reason I carry 9mm is because that’s what my wife carries. The main reason I carry Glocks is because that’s what my wife carries. I can adapt myself to just about anything. She either can’t or won’t be that adaptable; but it doesn’t matter which. I’ve never been able to make her do anything she didn’t want to do since the day I met her. It is important to me that she be able to handle my carry weapon if something should happen to me, even though she always carries one herself.
I have my personal range of calibers which I view to be “sufficient”. What does “sufficient” mean to me? It means that I have complete confidence that it will be enough caliber, if I do my part. Calibers less powerful than 9mm may be “sufficient” in other people’s hands, and those people may have complete confidence in them....and that is fine for them. But in a pinch, I’d rather have even a .25 than no gun at all - Jeff Cooper’s wisdom notwithstanding. I’d take a .22LR over a .25. I’d take a .32 over a .25. I’d take a .380 over either a .25 or a .32. I’d take a .38 +P over a .380, a .25, or a .32. Notice that I did not eliminate the .22LR? What that means is that I regard the .22LR as a legitimate self-defense caliber, even if it isn’t an immediate fight-stopper. I can carry 38 +P in my .357 magnum revolver, but I don’t, I carry .357. Why? Because in the unlikely event that I actually have to shoot it, I’m not going to give much of a hoot about recoil, but I WILL give a hoot about effectiveness - and a .357 magnum has a higher probability of being effective than a .38 +P.
And that is what this all boils down to for me. I don’t mock the less powerful calibers, but they’re not my primary choice for carry. If it were less socially awkward to openly carry a loaded long gun everywhere I went, I’d probably give less thought to what pistol caliber I carry.
