I carry 357 magnum revolvers of different sizes and use different grains for what in doing. Example ill use speer short barrel 135 grain or hornady 125 grain flex tip in my m and p 340 amd ill go all the way up to 180 grain hard cast in my 686 plus when im around big gators here in florida. My issue is the fact that if youre a good guy and and an armed bad guy has to be dealt with, it doesnt matter what caliber you use if you get the wrong prosecutor hes going to spin it like youre the bad guy! If you carry 9mm and shoot the bad guy 5 or 6 times its too many shots ,if youre me and hit him twice in the center mass it's the caliber I used. What if im walking my 20 pound dog near a water area and I bring my 180 grain hardcast just in case and the gators stay away but a psycho human comes outta nowhere and tries to rob me with a knife and I shoot him. Now im screwed for the ammo I had in my gun for gators instead of the focus being on the fact that this pos tried to rob me.
