As I said before almost any pistol can be modified by a criminal to bust a light vest.
I'm greatly annoyed that 357 AP was criminalized. It was the perfect thing to give deep penetration in a handy backpacking sized weapon. Without steel (which is too dangerous to give to serfs) you dont stand much of a chance of breeching a bear's cranial vault with a light sidearm). Thanks to panty-wetting hysterics like yourself I have to lug around a full 44 mag.
You might look into heavy charges of W-296/H-110 behind 160 gr. silhouette bullets (Hornady?). They penetrate pretty well.
