I have been carrying for about 2 years and I've tried everything from Shields to Glocks to whathaveyou. I have settled for just a 442 that I've been carrying for many months now. No more rotations. Just one gun. Same gun each time. Everything else have become range toys.
A guy at my local gun shop who used to be either a SEAL or some type of special forces, and is an expert on all things guns and combat related, tells me that you won't stand a chance when it comes to the the government taking us over or a zombie apocalypse. Besides, anyone who's ever watched a Steven Segal movie knows real men only carry 1911's!
Actually after owning just about everything under the sun, I've come to pretty much the same conclusions as you.
