Fortunately, we have trained professionals such as you two fine folks to set us all straight in this 100% serious thread based on an undefined scenario in which the average joe schmoe has to prepare for war.
But seriously, this thread isn't meant to be taken that seriously, as it represents an extremely unlikely scenario in which we all have to fight for our lives with whatever we've got, with the focus being on pistols of all things.
If you read the OP you'll see that this whole thread is based on a rather strange statement I've seen folks make in threads about their carry guns not being their first choice as something they'd bring into battle, as if such a thing even exists. It's basically a silly, sarcastic question posed for fun as an excuse to show off whatever pistol they fancy or otherwise consider to be their most combat effective option.
Rest assured, we'll leave all the fighting in your capable hands, this thread is just for fun. Thanks for your service, lugging around all that heavy equipment and marching into battle, so that we don't have to!
