This is always the debate. Sometimes the hollow points do "plug" and go straight through like an FMJ would, but I still like my chances with a hollow point. Better ballistics and less liability for over penetration, especially in larger caliber guns usually carried in the winter, as we wear more clothes and can conceal a larger weapon. As for me, I just recently changed from Black Talon/SXT rounds to the new Hornaday Critical Defense ammo. I carry it year round in all of my weapons, from .40 to the .357 or the pocket .380. The rubber tip in the cavity is supposed to help with expansion through heavier clothing, and the tests I have seen have convinced me. They also seem to feed much more smoothly in the automatics than some sharp ended hollow points, such as the Golden Saber.
