Do you wear a 5 point harness, a nomax suit and a hans device with a helmet when you drive?
Same concept
Same reason we all do a hi cap 9 isn't a magic talisman
That really doesn't hold water as an argument. Why then do you wear a seat belt, have air bags, have frames on cars that are now designed to keep the engine from crushing you?
It has been determined that those are reasonable equipment for helping you survive in most accidents.
Experts in civilian gun usage, which I assure you Kleanbore and myself know, have shoot with, have studied with, plus studying the literature and visual incident reports, taking part in high end simulations and FOF run by experts and competed in matches - conclude that for the tail of the incident intensity distribution, a standard rig like semi with 10 rounds and an extra mag or two is a reasonable criterion cut (as if you were determining the statistical significant level based on useful effect size) for the incident distribution we might face, ranging from a no shot DGU, a one or two opponent situation to a rampage horror show.
Thus the nomex suit argument is cute but doesn't really add anything to the analysis. Having a 10 round or more gun and an extra mag isn't that extreme.
One carries a smaller gun because:
1. Dress convenience - you accept that you have a gun that doesn't really give you a multiple opponent, longer time in the fight gun.
I understand that and if you acknowledge that without the snark, it is understandable.
2. You are posturing about how you can do the job with one shot or two. We hear that a great deal. I can make a head shot under pressure as I can do it at a slow pace on the square range.
I'll go out with a J or a G42 if circumstance mitigate that. However, I have shot Js and the 42 in classes and matches. It is not optimal, even though I shoot them well.
