That said, modern ammo developments have closed the gap between 9mm and .380.
No gap has ever been closed by advancements in bullets between two chamberings. The 380 is still 10k psi weaker and less case capacity. Same for "with modern bullets 9mm has closed the gap on 40 or 10" No...its still the same gap. Same deficit on sectional density and same deficit on ft lbs.
With modern bullets the 380/9mm etc etc has closed the gap on what is acceptable penetration in gel or through barriers. Or acceptable expansion on targets. That I agree with. But no ground has been made up on the 9mm. The 9mm gets every modern bullet the 380 gets. And still has more case capacity and max psi. Plus cheaper ammo
Between the two, as far as carry, I would carry whichever I shot better. If both are equal then I'd carry the more capacity unless maybe you live where thick winter coats are standard. Then I might go for more power.
