Rare BYF P08

[lugerP08thomas]

Has anyone ever seen this one, and can tell me more about it.



Any info is welcome

[alanint]

If looks like a WW2 era Mauser with a gunsmith turned barrel and home made suppressor attached.

This is not a factory offering, but something someone put together.

There is nothing really rare about it.

[DavidJayUden]

Not to mention, most likely, just a tiny bit illegal...
But an interesting job. Those that come back around the barrel behind the point of attachment are quite a bit more involved to make and more efficient than the simple screw on cans.

Is the barrel base near the receiver also threaded or just the muzzle area?

[lugerP08thomas]

Only the front is threaded (muzzle)
Me was told that's an original one, but i can't find info...

[Edward Tinker]

it might help to tell people you are in Belgium and its illegal or legal there...

[lugerP08thomas]

Will keep it in mind, but the item is not mine, i had to possibility to buy it but it have to be made DEKO as it's otherwise illegal also in Belgium/
I was thinking of buying it but as it's not an original one as people say here, i'm not goin to buy it

[DavidJayUden]

An interesting piece that I'd love to have a closer look at. Note the thick barrel base. This may not be "original" but it isn't a complete garage hack-job either.
Are there books that cover "original" supressed P08's?

I can get more pictures if you want, just tell me about what you want a pic.

I have never seen that type of supressor but it makes a lot of sense. I suspect the thick barrel base mates with a corresponding bevel on the rear of the supressor to provide a gas seal. The whole configuration provides a much more compact arrangement since it gives essentially an extended length supressor without hanging it on the end of the barrel. I'll bet there is a patent document out there someplace. A really interesting concept. Thank you for posting it Thomas!

It is designed in the same vein as the Sten and M3 cans of WW2 and the Mitch Werbel units made in the 1960s.

This design would have been much more effective if they had also ported the barrel, allowing gasses to gradually bleed off into the suppressor body emcompasing the barrel. It is of a stacked baffle design with two full lengh guiderods for baffle indexing.

Sadly, it appears to have been hidden away for some time and has suffered accordingly.

Are there any indentifying markings on it?

[alanint]

Ron, A seal at the rear would only be needed if the barrel was ported. As it appears, the seal is at the front threads and the rear portion of the can only provides gas bleed off volume space. The rear barrel ring merely provides support and to a lesser extent, bore indexing.

A really professional job would have an a front sight added to the breech area. I'm guessing Belgium Resistance manufacture.

I can see the advantage of this suppressor in terms of stability in mounting, and perhaps balance of the whole thing, but I think it would not be as efficient as the entire length hung off the barrel. One key of max efficiency of a suppressor is permeability of the medium surrounding the bullet's path, and surface area would figure heavily into this. Yes, we have again as much volume in the structure behind the muzzle, but access to it is restricted to the I.D. of the outer tube, minus the O.D of the muzzle, sectioned at the muzzle, when this surface area is calculated. But it may be that the pressure is developed in the system quickly enough that my point may be negligible. Anybody know for sure?

[alanint]

Stability in mounting and added can volume for gas cooling/dissipation is really all the advantages this design offers.

The most efficient method of taking full advantage of this type of design would have been the ported barrel that I mentioned previously. Gas bleed-off through barrel porting offers several advantages;
- Quicker cooling of exhaust gasses
- Gas velocity deceleration/cancelation when ported gasses meet muzzle gases inside the can
- Larger gas containment volume with little added OAL.
- Muzzle velocity of the round dropped to subsonic levels prior to leaving the barrel, elimination sonic crack and allowing the use of standard, issue ammunition.

The MP5SD is a good example of this ported barrel inside container design, still in use today.

This can was designed with little understanding of suppressor dymanics and the added weight may have made this setup a single shot, hand reloaded affair.
Has it ever been fired to acertain this?

[DavidJayUden]

Typically on these designs, and the ported integral barrel models, the gasses are first sent into the rear chamber, usually dampened with a series of ports, tubes, or packing materials such as steel wool, etc. Then it is vented to go into the front section, which is simply a series of baffles designed to slow the escape of the gasses. The tighter around the bullet the better, with "wipes" being best in some regards, but not others.
My rule of thumb is that volume is what makes a suppressor effective, not all the fancy plumbing/ machine work. If you want to make it quiet make it bigger, and this one has utilized the area behind the muzzle to increase volume.
Porting the barrel to send the gasses directly into the rear chamber is always preferable, however it requires a dedicated unit. The best units for that app. are those with removable barrels, so you can simply remove the standard barrel and screw on a new barrel/suppressor unit. Much like those used on the S&W 76 (MK760) SMG's.

Ruger MARK I,II, III semi auto pistols (.22 LR) silenced are around and I have shot one. No noise at all.

However, to silence a WWI or WWII Luger to shoot a 9mm Luger is sort of beyond the stretch for me. I figure it is an anomaly.

It is worth what it's worth to the one buying it. It is not regular.

[alanint]

Not so difficult with modern suppressor design using K baffles and other advancements. My MP5 can be used with a Gemtech Raptor muzzle can and a special recipe of 147 Grain ammo and all you can really hear is the bolt clacking and brass hitting the concrete at the range.

I've not heard of a 'K baffle'...Does that refer to the shape, or composition, or something else???

[johnii]

My input is you can silence a .22LR in a Mark I or II or III Ruger. There is a shroud over the whole barrel to do it.

Silencing a .22 short is easy. Silencing a .32 ACP is actually more difficult as they show on movies. There are silencers for .32 Walther ACPs in the Walther designed to screw on the huge after piece.

Now you want to say you can silence a 9mm Luger as if it makes no sound at all with a foot long silencer.

I figure go to it but don't expect me to buy it. I'd just use a .22 LR with a silencer or .22 short or maybe, maybe, a .32 Walther PP or PPK.

Silencers are over rated. You shoot a bullet out of a revolver or auto that is bigger than a .22 Short you are in for noise. This is a non argument to me. You cannot silence a 9mm Luger like James Bond does with a .32 ACP. And even that is subject to question. Maybe a .22 Short? I'll buy that.

Yes, it refers to how it looks in cross section. It is more like a "K", with a truncated spiral channel, which redirects and slows the gases.
