I know that .380 rounds have come a long way. And I know that very small 9mm weapons warn against using +P ammo.
But in like sized weapons, which would you choose? A 9mm standard pressure or .380 plus P?
Contrast for example the Diamond Back 9mm which warns against +P ammo, and the Sig Sauer P380 which allows + P but in .380 ammo.
(I would take the 9mm personally).
