.380 is stupid, and will not sell. Should have been 9x18 mak.
9x18 is still cheap. I doubt that 9x19 is possible in a scorpion..380 is not stupid as it is the "hot potato" round right now. Consider all the .380 pistols in the current market. 9x18 is dead as even the Russians are using 9x19 in their newest models. That would be a good choice.
+1.380acp is a big improvement over .32acp
