The Russians, East Germans, Poles, etc. all used the 9X18 Makarov as a police and military arm for a long time and it is hardly more powerful then the .380. Agreed, the more powerful calibers will do more damage and will serve at longer ranges. But in a CC size firearm the .380 is about all most folks want to shoot. I once had a Beretta Minx in .22 short(swapped it off, darn it). I would not want to be on the receiving end of that, let alone a .380.
