Yes, 380s are small frames but they are still a 9mm (short)
the 380 and 9mm are actually .355
Other names for .380 ACP include
.380 Auto,
9mm Browning,
9mm Corto,
9mm Kurz,
9mm Short,
9×17mm and
9 mm Browning Court (
The USA gets all befuddled with the metric system,
9 x 17 vs 9x19
What made a lot of them "snappy", is that they were blowbacks and not locked breech.
Is a 40 SW a 40 caliber or is it still a 10mm.
