Why my primary and backup gun share the same caliber

[I_am_groot]

he logic here is pretty straightforward once you actually think it through, if something goes catastrophically wrong, I want shared ammunition between the two guns rather than two completely separate logistics chains to worry about. It also means the handling characteristics carry over between platforms, so I'm not relearning anything under stress.

There's just no good reason for a backup gun to introduce a different manual of arms or a different ballistic profile when the whole point of having a backup is to remove variables, not add them. Standardizing where you reasonably can just makes sense because complexity in a crisis isn't neutral, it's a liability you're choosing to carry around with you.

Does this make any sense to anyone?

Yeah, that makes sense. Same ammo means less hassle and fewer things to keep track of especially when things aren’t going right.

Completely agree. In case of need, I have one of my AR's in 10mm, and four of my pistols in that caliber!
