WTF is this thing?!?!
 
It's a sound suppressor for an artillery testing range in Meppen, Germany. The range is, IIRC, quite close to an urban area, so the suppressor is used to limit the impact of the facility on the nearby inhabitants. It's not unique, even; there's a similar rig at a range in the UK, but my google-fu is weak tonight and I can't find a picture of it.

How do you supress a revolver? What about the noise producing gas escaping from around the cylinder?

You build it so that there's a gas seal between the cylinder and the barrel. The only production revolver I know of that does this is the Nagant M1895, which used what is essentially a case-telescoped cartridge with the bullet seated slightly back from the lip of the cartridge. The cylinder cams forward as the hammer is cocked, forcing the slightly protruding mouth of the cartridge case into the barrel and producing a gas seal. The rear end of the barrel also slips into a recess in the face of the cylinder, so the case is supported.

It claims only that "the muffling of the noise of the report should go from 136 to 90 decibels, about the strength of the report of an air pistol".
But as a circular saw or a lawnmower produce about 90db, that's still pretty noisy.

See the big half-cylinder thing sticking out the left side? That's a "muffler" that fits around the cylinder (presumable another on the other side, forming a "clamshell"). Cylinder can leak all it wants, if it leaks into something that dampens the sound.

Seems like a lot of effort to go to. But then, so's the suppressor for the artillery piece.
 
What the hell is that, and for the Love of God PLEASE don't let it be what I think it is!


Sorry, but I was just reading off of Gizmodo about how they're selling Dora-themed sex toys...yes, it's wrong. No, I can't do anything about it no matter how badly I want it to stop.
 
so Wat? we German have The "bigger" one <jk> ;D

A lot of effort for the revolver, but in the blurb to the side it states that it fires a .45 ACP cartridge, and that sound reduction is from 136 decibel to 90, which brings it to the sound level of a pellet gun. That's pretty damn impressive for a full caliber surpressed weapon.

Somewhat different concept but another way to "silence" a revolver:

The same basic concept was used to develop 12-gauge shells for Navy SEALs during Viet Nam. They worked (reportedly reducing the sound of the shotgun going off to "clack"), but were too expensive.
 
Probably the quietest was the WWII de Lisle carbine

The most important step is to use subsonic ammunition.
 
A weapons magazine I used to read when I was in my teens ( the dutch SAM) stated that while very quiet the Lisle was a bit unreliable because o the thin build of the silencer. Still a very interesting weapon.

The Russians have a whole range of weapons using this concept, see e.g.:

Interesting concept (read: geeky) ;D
