Suppressed revolver from Knight?

[Ovid]

Hi all, I guess I've got too much time on my hands today, because I am sitting around thinking about unusual guns...
I remember reading about a suppressed ('silenced') revolver from a company (or individual) that was IIRC named Knight. I believe it was either based on Ruger's GP-100, or SP-100. I've never seen a real photo of this gun, I've only seen a crappy drawing of it in an old RPG book. Does anyone have any photos, or information on this firearm that they would like to share? I tried looking on the net but no luck.

Knights Armarment made it. Specs are in the link:

I think the 4th edition of the gun digest book of assault weapons has a write up on it. Made up on a GP100.

There's a picture here:

wouldn't that require tons of modifications?

You would have to seal the gap between the cylinder and the forcing cone correct? Otherwise the gap would alow gass, and thus sound from the combustion, to escape.

They could have just threaded the barrel on a Nagant revolver and used an existing silencer, but I suppose that would have been too easy.

IIRC the gun was built to a military survival rifle spec for a quiet gun that wouldn't leave casings around. The cylinder gap closure is accomplished by using modified ammunition that has a sleeve that pushes forward upon firing and seals the gap.

My understanding is the same. The round was a .44 magnum necked down to .308, and the brass obturated over the barrel/cylinder gap to seal that area. The Russian Nagant revolver uses a cylinder that moves forward so that the forcing cone is INSIDE the cylinder at the moment of firing. Weird.

Course not as weird as the CIA 'issued' .44 mag "telescopic " round. These babies kept the BOOM inside the sealed short case. The folds expanded into forcing cone then retracted back into cylinder accelerating the bullet. The bullet was 200 grains metal case and velocity was supposed to be about 700+ fps out of the 4" barrel model 29. I've actually SEEN an expended casing or two! These were tried in the Iron Triangle area tunnels around 1970-71 under SOG control.
