450: Frame sizes of many modern pistols are not quite deep enought to handle the length of the round. Not sure about the 1911,as I don't own one anymore. The Browning GP/High Power is too short, but was chambered in .30 Luger and they can from time to time be found on Gunbroker in that caliber etc. It isn't quite the 7.62 Tok, though.

The leather thing idea sounds do-able. I use such a gizmo on guns with weak FP's like the CZ52 for dry firing, so I see no reason why such a "block" wouldn't work as a safety. I make my own holsters, so I guess it wouldn't be too difficult to arrange something to act as a safety.

Paati: I and some friends have had several CZ52's. All of the guns we owned had very hard triggers, and the mechanism is a bit tricky to work on, though the pistols are accurate, just as you say. My current Tok is a Polish model that is very well made and has proved to be as accurate as the CZ's we had. I had a Norinco Tok that placed its first shot about 6 inches high at 15 meters {slide lockup issues}, then clustered the rest in a nice tight group below it. I got rid of it.

Also, over on the gunboards forum there was a poll of CZ users experiencing cracked slides. Slides seemed to let go at at about the 4,000 round count, and when they did they cracked at the roller lock recess on the slide which is the thinnest portion of the slide. I suspect some of these guns were shot extensively with certain lots of very high pressure Bulgarian subgun ammo that came into the USA some time ago, but I can't be sure. Some suggested that due to the radial locking lugs, the Tok might in actuality be stronger. I am not too sure about that. I used to shoot a lot of Sellier & Bellot FMJ from my CZ, but at 1550 fps it is a petty hot load and I use such sparingly in the Tok. Mostly I shoot Wolf "Gold" {actually, loaded by Prvi Partizan in Serbia I believe} 85 grain Hollow Point from my Tok.

What load do you shoot normally? Do you handload for it?

Both the CZ52 and the tokarev are very flat and easy carrying pistols. I carried my CZ many miles on my skis in the winter time, but now the Tokarev has taken its place. I like those pistols, but I'd like to see a modern, flat, steel-framed version. I doubt I ever will...
