I can tell you about it...
My Norinco Tokarev is 38 years old and I've shot well over 10,000 rounds through it. NEVER a FTF or FTE. I've shot Bulgarian, Romanian, Chinese as well as S&B and Wolf ammo without any problems. You can buy Bulgarian ammo for about 10 cents a round.
You can buy one of these without having to use an FFL, as Tokarev's are classified as C&R guns today. You can also get one for less than 200.00 at places like J&G Gun Sales.
The 7.62x25 round is very potent and close to the power of a .357 Magnum. And it will put 9mm to shame for penetration.
I added a muzzle brake to mine and it works great! The thing I really like about the Norinco Tokarev is it's cheap to buy, cheap to shoot, and its very, very reliable.
