How the P-08 Luger Works

Using an MGC Luger "model gun" I demonstrate the delayed-blowback operation of a real Luger. Don't worry, this is not a functioning firearm.

is the ejection port bigger on the model to clear the entire round as opposed to a spent case? that seems like a whole lotta space up there.

[taofledermaus]

@mrbadx19 I never thought of that. I assumed it was to scale. But even the real one- you'd think it would allow an unfired cartridge to eject too.

Heh....I've got a real one in my closet. I'm on the opposite coast from you, however.

[taofledermaus]

@desertfox2020 Dang it!  I'd even buy you a box of ammo to use.

Functions like a .45 Browning, just a tad different idea about how to lock the barrel to the slide or bolt. Does the barrel move before the bullet exists the barrel?

[taofledermaus]

@RayetWolf Not sure. It probably moves slightly.

@taofledermaus You still interested in high speed videos of a luger? I'm going to film one this weekend, in 450 and 1000 fps, the quality of the video is quite bad though, like 360p or even less with the 1000 fps. I could send you the footage if you want it :)

nice!

How much would you want for this one here? Just name a price.

[demonofrazgriz333]

not delayed blowback, it's a toggle locked recoil operation

My dad left me a byf42. I haven't fired it but it still operates just like this ...

@RayetWolf

Btw, this taofledermaus is wrong attributing P08 to guns with delayed blowback operation.

It's recoil-operated (see Wikipedia for details)

@RayetWolf

Bullet accelerates in barrel for 0.001s. In THIS 0.001s slide accelerates back to 2-3mm, &then decelerates during 0.05s on distance 1-2cm to stop &to go back. That's why u have to record at 10,000 fr/s to see full dynamics.

if barrel doesn't move before bullet leaves the muzzle, it won't move after because the gun is either gas operated or has a motor for reloading. I tired repeat: u can't avoid law of physics.

My English is too bad, or u haven't learnt natural science in school.

[RayetWolf]

@currishev See, the slide or barrel (depending on gun) moves before the bullet exits the barrel. There are those who argue that the slide/barrel doesn't move before bullet leaves the barrel. They even have modeling concepts showing that.

[currishev]

@RayetWolf

I humbly repeat after Newton: as bullet start its 100mm (for P08) travel along the barrel, the slide starts recoil. To see it, fix P08 into heavy mount with ruler &record shot at 10,000 frame/s. U'll see as tip of bullet shows up, the muzzle has moved about 2mm.

Reloading needs the energy gained either from gas or recoil BEFORE bullet leaves the gun causing pressure drops to atmospheric &gun has no energy source.

Only Chain &Gatling guns have motors to operate.

Stop B.S.-ing

@RayetWolf It is not difficult at all to call yourself a gunsmith. Heck, I could call myself one- I spent a couple years in high school as a gunsmith's helper.

In the end, a gunsmith is someone who claims they can fix a gun. Having spent all of my relatively short life in the firearms industry, I can confidently say that probably only 1 in 5 gunsmiths have any real comprehension of what they work on.

Most just clean guns, screw on scope mounts, bugger screws, and replace common wear parts.
