Around 1995 I was talking to an instructor from the Treasury School near Brunswick, GA. The conversation turned to the CZ-52.
I told him about an article I had read in “The American Rifleman” about some of the hot ammo which was apparently safe in that pistol but probably not in a Tokarev.
He said they got a hold of some of that hot stuff and tested it on a bullet proof vest. I forgot to ask what it was but he said that 7.65X25 went right through it.
