Suppressor for shotgun...

[Ken]

Anyone ever seen a suppressed shotgun?
I found a picture of SPAS 15 with suppressor:

I doubt someone tried to suppress a shotgun. Maybe you saw a choke or duckbill, but not a suppressor. If you loaded typical shotgun loads (buck shot, bird shot, etc.) it would be impossible to suppress the gun.

OK. I just visited the site. Fuck me, a suppressed shotgun. Oh well.

Suppressor for shotgun....seriously doubt it,however as a side note I have heard of "suppressed" shells made some time ago, I think it was in fact an experimental thing for tunnel rats in Vietnam.

I don`t know about tunnel rats but I think it was Kevin Dockery`s book "Special warfare, special weapons" in which was about suppressed shells and SEALs experimental use of these shells in Vietnam. The idea of these shells is that gases never leave the shell. Of course this has not so wanted effects, e.g. loss of power.

I live in the same town as BR-tuote. I know the owners and their suppressors are not expensive,they are very well made and easily available.

The "suppressed shells" mentioned were the TeleShot rounds they used during Viet Nam. It worked basically by expanding a telescoping metal tube up through the barrel which pushed the slug out the barrel. Never heard of them being used much after the war but ANYTHING is possibile. The one refrence I have to their effictivness came from a friend of mine who served back then.

Basically they worked well, most of the time though the teams that used them were also equipped with other suppressed weapons (aka Sweidsh K's, etc). I've seen pics similiar to the one described-with some sort of reflex suppressor affixed to the shotguns-probably the same site your refering to Ken.

Interestingly enough KAC has been working on a revolver which uses telescoping rounds-suppressed of course. It makes for a very interesting looking weapon-but not heard a thing about the weapon so far. If no one's seen the KAC pistol let me know and I'll post it so you can see it.

The Russians have a suppressed weapon that uses the telescoping ammunition. The piston doesn't actually go down the barrel, it only extends the length of the cartidge case. I can't remember the name of the weapon, but it is a semi-automatic (and perhaps full auto) weapon with a high capacity magazine. It doesn't have a supressor in the conventional meaning of the term. The gases are contained within the cartidge case, thus alleviating the need for a supressor.

Yep I know which your refering to reece_o. The PSS I think... I actually have information on that one-kind of interesting how they designed that one. Ranges are reduced but then if your using a suppressed weapon your going to be upclose anyhow...

First, folks are working on shotgun suppressors. One model from Young Manufacturing was even demoed at the recent Suppressor Trials sponsored by Small Arms Review. They are also working on subsonic shotshells _and_ integrally suppressed barrels for the Remington 870. New River Arms (http://www.newriverarms.com/) is handling sales and distribution of the shotgun suppressors for Young Manufacturing.

In another recent issue of SAR, Reed Knight and his staff revealed that they are working on a Dutch military contract for a suppressor for a 25mm automatic cannon which uses sabotted ammunition. The discarding sabot provides much the same problem as the multiple projectiles in a shotgun. If KAC/KMC can successfully solve the problem on the 25mm cannon, the same technology should be able to be scaled back for a shotgun.

Speaking of KAC suppressed revolvers, the KAC cartridge design is different from the Soviet piston cartridges. In the Soviet designs, the gases are sealed in the case by the piston...no suppressor is needed. There have been three generations of pistols (each with their own cartridge type) and a 'silent' grenade launcher. The technology has been established to where the piston cartridges can reliably operate semi-auto mechanisms. (Click on the links to see thePSS pistol (http://ia.vpk.ru/vpkrus/homes/h109/eng/pcc.htm) and the BS-1 grenade launcher (http://kalashnikov.guns.ru/models/ka118.html).)

In the KAC designs, the revolver uses a sleeved projectile in a larger case. However, the bore of the barrel is only large enough for the projectile. Thus, the sleeve stops against the forcing cone and acts to seal off propellent gases which would ordinarily escape through the cylinder gap. The weapon still requires a standard suppressor.

The cartridge design used by KAC was originally developed by Bob Olsen in the mid-'80s. Olsen created the .257 and .358 Invictas, based on the .357 and .44 Magnum cases. The idea was to use them in Dan Wesson revolvers with the teir easily changed barrels. However, someone eventually realized the safety/liability issues involved...Joe Doofi would forget that the .358" barrel was installed and attempt to fire a standard .44 Magnum. Ooops!

Suppressors for shotguns have been around for a looooong time. When I began to dip into the Class III stuff, my granddad told me about a suppressor his dad had for a shotgun back in the '30s.

They haven't caught on because they are big, heavy, not very pleasing from an aesthetic viewpoint, and, well, they just don't work. At least not as well as one would like.

There has been some improvement in the last 10 years or so, as noted above, but they still have some challenges to overcome.
