ColtDriver,
I have used .22, 9mm, .45 and all of them are exceptional. I have not had a .380 to shoot but have corresponded to several folks about the .380 ammo as well and in addition to it being "explosive" like the other calibers, each of them claimed it to be quite a bit more accurate than other rounds! Some folks claim that .380 is inherently inaccurate but the folks who used the Quick-Shock claim it is as accurate as they are with the best pistols they have shot in other calibers...
