"The need for high capacity means I am likely in the wrong place to begin with and did not pay enough attention to my area before I walked into a war zone."
If you choose to carry a revolver with six or five round capacity, that is obviously your choice.
But please do not attempt to put forward such inadequate arguments against carrying a semi-auto.
Be prepared means, be prepared.
I prefer to carry a Glock 26 with 14+1 and an extra 14 round magazine, with the best +P JHP ammo I can buy. I feel more comfortable having that kind of capacity and capability. You may not prefer that.
But suggesting people who carry semi-auto are not paying attention or are in the wrong place is a fallacious argument.
