I think its wise to have guns that use the most common calibers. You never know it ammo will be hard to come by and its easier to find 9mm and 12 ga then anything else.
I have a 410 shockwave and i struggled before this virus finding good ammo
To be honest 45acp is very prevelant in the US.
And the most common round is probably the 22lr.
I wouldn't trust my life to 22lr and 45 just seems dated and not worth the size penalty. imo.

OT:
To my firearm guys.
I mentioned the stribog, but the more I think about a PCC, the more I ask myself, why?
So I'm thinking, should I go with a 300 blackout AR build or go with the stribog? Opinions...
