A good bit of reading about my CZ-82 and its commercial version, the CZ-83 in .380 Auto leads me to one conclusion:
There must not be any operational differences between both guns, with most parts (not just mags) common to both.
And if there ever were a ban or high tariff placed on imported 9x18--almost all of the imported varieties seem to be from Russia--the 83 (.380 Auto) would allow us to shoot at a lower cost than using domestic 9x18, assuming that .380 Auto ammo is left alone by our political Apparatchiks.
