I've put close to a hundred rounds of hardball (not watered down loads either) through a 45 acp American Derringer. I've found the recoil to be brisk, but not un- managable. As far as accuracy goes, I can make a very dangerous coffee can pretty uncomfortable at 15-20 feet which is probably good enough for most social situations. The repeat shot can be done quite rapidly with a bit of practice also. I don't know if I would go so far as to call a derringer a good choice for concealed carry, but if I didn't I sure wouldn't give my vote to any of the 32's either. I sure woudn't want to get hit (or shoot anybody either) with either of these cartridges, but one good hit on an assailant with a 45 (even with the diminutive length barrel) would in my mind be preferable to several with the 32's, besides, who says your going to have time to make more than one good shot anyway?
