Stuff like this is why I believe that people pay entirely too much attention to energy numbers.
All other BS aside: will they cycle your pistol. Every other concern is in line behind that.
Penetration? By it's very nature, frangible ammo is going to be a bit squirrely where penetration concerned. Seems to me that heavy clothing or ANY barrier could result in completely unpredictable behavior. Just my $.02, but I'd stick with time proven designs where my well being is concerned.
FWIW, I'm on the "bigger hunk 'o' lead" bandwagon. When I carry a .40, 180's are on board. YMMV.
