how is this to be determined? the one I shoot the most? 9mm. The one I stock the most live ammo for? .22lr. the one I carry the most? 356 TSW. The one I'd want for shtf? 356 TsW, but have a spare barrel for 9x19. Shtf, handgun use better be really rare, cause everyone will have a fighting rifle (if they've survived more than a week or 2) A handgun vs a fighting rifle is a bad, bad place to be. Just ask the 7 Feds that Platt killed or wounded with his Mini-14, after he had been wounded and could only use one arm.
