AFAIK, one of the other drawbacks to the Tokarev is that the muzzleflash is extreme, and could have ruined a soldier's night vision.
It will still punch right through a k-pot helmet, though, with regular ball ammo...which is something few handguns can claim.
Also, the fiveseven's actual armor-piercing ammo is not sold to the public. With the Tok, the regular ball is armor-piercing, since it leaves at over 1600fps.
