rendering Bricktop speechless might be grounds for turdlike status...

VAnimrod,

Are we gonna get to see some pics? I keep going back to this thread hoping to see some photos or read some range notes, but....

Wouldn't the CZ 52 have a stronger lockup than the Tokarev?

The lock up is not the problem. Both the CZ52 and the Tokarev could have been blowbacks. They have enough slide mass and case support for the cartridges they were chambered in for blow backs to work. Maybe the cases would have ejected a long way, but it could have been done.

The problem with the CZ52s are:
1) The thin spot under the chamber where the relief cut for the rollers was milled out. This causes the CZ52 chamber to split at relatively low pressures compared to any other semi auto.
2) The heat treat of the barrel steel varies from RC25 to RC47.
This causes the chamber to split much more easily on some CZ52s than others.

I have thought about making a CZ52 barrel out of good steel with good heat treat and slightly less cut out for rollers. I could use slightly shorter rollers. The CZ52 might get stronger than the brass, and join the ranks of every other semi auto pistol.

Pics, I can get today.

Range notes will have to wait a bit. The indoor range here in town does not allow any bottlenecked cartridges, so... a range session will have to wait until I can get clear of town and up to the hunting camp.

Got all the cosmoline cleaned out of the M57. Overall, a very nice little piece. The trigger (once the cosmoline was out of the firing assembly) is pretty crisp; heavy (maybe 7# or so), but crisp. For a battle pistol, that's not bad, not bad at all, really.

Still waiting for Clark to comment on exactly what PSI pressures his bomb-load Tokarevs are withstanding...

A blow-back in 7.62x25.... priceless....

You think you deserve data?

I believe you can buy 7.62x25 blow backs.

You think your "experiments" are credible without data?

You might be able to buy a 7.62x25 blowback; gotta link?

I don't think most here deserve your data.

FWIW, and this is apples to oranges, but you can get at least one blowback 7.62x25
Wiselite is the shop putting out the new Sterling Carbine(9mm Para) thery are also now producing the Wiselite Colfire Magnum Pistol. Essentially a chopping down a Sterling Carbine in to a pistol and chambering it for 7.62x25
Like all Sterling/STEN it is a blowback gun. They have been available for awhile now. I can't give a link from the office, but J&G in Prescott, Az. has them.


That said I still think Clark is blowing smoke here.

Wow....

Yeah, this thing SO resembles a Tokarev or CZ-52... it's just glaringly obvious how those guns could have been a blow-back like this one....

Well run company, too....

Like I said apples and oranges.
Just clarifying that there is at least one blowback in 7.62x25

I wasn't backing up Clark in anyway....

Oh, understood completely.

I'm not an expert by any stretch, but the full auto versions of the Sten and Sterling fired from an open bolt, not blow back. The semi-autos are closed bolt, but I'm pretty sure the Sterling has a fluted bolt and is at least a delayed blow back, if not a locked breech, firearm.

Pardon the crappy pics (a photographer, I ain't...):

Let's start with a couple "extend family" pictures:





Now, obviously, that's a Colt 1911A1, a BHP (FEG-clone), and the Yugo M57. The family resemblances go much more than skin deep, however.

Here's the 1911 stripped:



Notice the barrel lugs, the takedown/slide release/stop lever, and the barrel bushing, along with the toggle link and recoil spring assembly?

Now, here's the BHP stripped:



The barrel bushing was eliminated, as was the barrel toggle/link assembly. But, the slide release/stop, the barrel lugs, and recoil spring assembly are very similar, as is the overall slide design itself.

Now, here's the M57 stripped:



The barrel bushing is back, as is the toggle/link. The barrel lugs are still there, the slide release/stop is still there, and the recoil spring assembly is similar (though, it's a 2-piece, jointed spring guide).

Look, though, at that modular firing assembly. Rather ingenious, really.

Even the magazines are remarkably similar and show the family traits:



If anything, the Tok is simply a much simplified Browning-derived design. Indicative of that is not only the modular firing assembly, but look at the retaining mechanism for the slide release/stop:

Just a simple locking slide; no machinations of the slide required to disengage. Clever.

They are a lever delayed blowback to my knowledge.
I could be mistaken as I have not laid hands on one.

Damn it!

Seeing these Toks all cleaned up is really putting the bug to me. I might need one of these.

Magnum...

They're damned cheap.... and even cheaper to feed.... Russian count case (1280 rds) for under $150. Try that with anything other than a .22LR....

Yeah I haven't been able to find one local yet. J&G is just up the hill in Prescott and has them for like $180.

I know the ammo is dirt cheap there too. Like $79 for 1000rounds or something silly.


Maybe roninphx wants to part with one so I can avoid the run up to J&G

+100 on this.

VAnimrod: Thanks for posting the great pics. Those Yugo Toks look nicer and nicer everytime I see one. Your photos might have just pushed me over the edge.
