bch, more than one CZ has had issues with hot ammo, especially with the rollers and roller recesses. That area seems to develop cracks at a rate that has convinced me to avoid the pistols. My TTs eat everything, and I have never seen a report of a TT having pressure issues; slide, frame, or barrel.
gunny, in my opinion, as a shooter and cartridge collector, that ammo has less value than other surplus Tokarev fodder. However, some less-than-honest folks are selling Czech surplus as rare AP ammo, which it is not, and asking high prices for it.
This ammo tends to cause a lot of consternation on these boards... the debate as to whether the CZ or TT can handle it better, is it hot, is it armor piercing, is it better and so on which usually spiral out of control.
My observations, and no further: Junk. I bought the stuff for a CZ and half the ammo went off 1 click, about 1/3 in two, and the rest just did not go off even after 3 or 4 hammer strikes. I don't care how great it is, it pissed me off. The clips are cool though.
