Mostly disagree, JohnSKa. Exception made to the Federal Mak round which is pretty lame, the other American rounds are so called "specialty" rounds. Extreme shock, Corbon, RBCD, etc. Fast by any standard.
Russian 9x18M ammo, for one, is closer to 9mmL specs than .380 to 9x18M specs. Silver Bear, for instance.
Btw, I use Fiocchi. $12.00/50. Not necessarily inexpensive. The sound of the Kachinn and the Kaboom disturb my concentration.
Kind of goes like this, "Ooops, there goes another quarter!".
