Tokarev Ammo and Penetration Tests
I live in Bear Country and we have the occasional nuisance bear (Black Bear and Grizzly). Due to the thick skin and thick skull on a bear I need penetration more than expansion. That said, there are 7.62x25 hollow points (Wolf Gold) and fragmentation rounds (Mag Safe) available.

Note that of all the handguns, the 7.62x25 is the only round that penetrated the helmet and water jug.
Wolf Gold JHP
7.62x25 Tokarev Wolf, 85-grain JHP, 1591 fps. Currently out of stock due to high demand but I understand that some may be imported in the Fall once again. Occassionally found on Gunbroker.
Mag Safe Fragmentation
7.62x25 Tokarev MagSafe Defender Cartridge, 52-Grain, 2120 fps and ~ 560 ft-lb at the muzzle. Mag Safe Frag rounds are pricey at just under $3/round. But they are currently available.
That said, When not carrying a Glock 26 or 19, I find myself carrying a small P-64 as my BUG (pocket gun) and a CZ-82 or German Makarov with 9x18mm Hornady XTP rounds (especially now that it's summer). 1000 feet per second with 211 foot/pounds of energy.
