The wife recently converted to the metric system .. her concealed went from a .380 to a 9mm.
Oh Lord, please don’t bring the clusterf-ck of caliber designations into this. Now you’re going to have to explain to everyone how the bullets in a .380 ACP are actually .355” in diameter (same as all 9mm cartridges. or are there some 9’s that don’t use .355 that I’m unaware of), whereas the bullets in a .38 Special are actually .357” in diameter. ;-)
Don’t mess with a 12 ga.
