yes, that seems to be a concern worth contemplating. I'll continue to consider pros and cons for myself. In the meanwhile, it's actually in my carry pistol now.
"Finally, while I am giving high praise to Polycase for blowing my mind in showing that a light and fast bullet can accomplish what I normally expect from a slow and heavy bullet, I confess to being a little uneasy about just how light the bullets are. The lighter the bullet, generally the more susceptible to deflection it will be, whether off of a bone or, bizarrely enough, just through gel or tissue itself. To me, that’s not a desirable trait, and I am not entirely convinced as to how these lightweight bullets will do when faced with having to penetrate through a forearm to get to the chest of the bad guy, where they’ll then have to get through a rib or sternum. They may do fine, but history and big-game hunters have taught us that big, solid, heavy bullets do best at that job done."
I had bought some 9 and 380 then finally went to the range this afternoon. Just shooting paper with a cardboard backing, at 7 yards no difference. At 15 yards it key-holed with the 9 but the 380 was less obvious. Accuracy was no different than any other ammo I use. The 9 feed without issue in two semi-automatics but those guns will eat anything. Last round of 380 would always fail to feed in a TCP 380 which oddly enough is the same issue it has with American Eagle ammo. Anything else feeds without issue in the Taurus.
