Just wipe “.380 replacement” completely out of your heads. That is a .32 ACP, in the case of bores. I’m not sure how else to say this at this point. The maths and physics are accurately covered in Louisiana high school, and we cannot simply will those sciences into irrelevance because we want a better pocketgun. The only thing we can get out of the tradeoff is more capacity at similar velocity and kinetic energy levels, in comparison to 9x19.
Aye... agreed. Just use what you have.... and get good with it. Competence can neither be purchased, nor, in this case, invented. And you already have everything you need.
