View Full Version : suppressor for gp100

is it possible and are thy legal---total curiosity

Possible? Yes. Effective? Not really. It is my understanding that revolvers have too much open space between the cylinder and barrel to effectively suppress the noise of firing. As to legal, that would depend on your local and whether or not you meet the requirments of ownership.

Dan Wessons are probably the best to try a suppressor on as they usually had the tightest cylinder/forcing cone gap. Still seems kind of silly to me.

FL is very NFA friendly.

FL is NFA friendly, but trying to suppress a revolver would be like trying to suppress my sister-in-law.......................It can probably be done, but it's not real effective. Too much gap for hot gases to escape through. The biggest problem would be finding a suppressor for that bullet size.

Tolerances in a 9mm suppressor should be plenty for the extra .002" of bullet size. Even if not, any suppressor manufacturer almost certainly reams their own tubes, so they could make it with no more than a couple of minutes extra work over the 9mm.

Revolver + Silencer = Hollywood ;)
Anyone who really wants a suppressed gun gets a semi auto.
There are exceptions IIRC the Mosin Nagant?, and some other foreign revolver of yesteryear had a mechanism that moved the cylinder forward sealing the gap when the trigger was pulled. They did make effective suppressors for these.
The GP100 will still be loud because of the barrel cylinder gap.

Knight Engineering produced/produces this take-down silenced revolver (based on a Redhawk), but I doubt very much they would sell it to anyone but the government; to get around the barrel/cylinder gap problem, it uses a telescoping 30-calibre cartridge that seals off the gap with o-rings of some sort. If you want an effective, commonly-available suppressor, you need to look at semi-autos.

just curious-learn something new everyday---lol about the sister-in-law crack--in the same boat--much understood

To any measure, some serious smithing would have to be done to either the weapon or the can to attach a suppressor to the revolver. Then if the weapon is an off-beat caliber, you'd either have to use a can made for the closest, larger, caliber out there or find a manufacturer that is willing to do a 1 off... and that ain't easy..... or cheap...
For the shear S&G's of it, if you've got money to piss away, then heck.. it'd be neat. It would deminish the sound quite a bit, but you'd still have to wear ears as that gap goes. Even with the shifting cylinders of old, a LOT of gas would still escape...
KAC's unit was a prototype to see if it could be done. They dont make that for market, and they wont 1off anything. Hell they price themselves so hight that they do not do many civilian sales (except for the ID10T's that want to fork out 2x's the money for something that you can get for 1/2 that price and beat it in effectiveness, but hell they are the largest suppressor manufacturer out there).
Several years ago someone did make an effective suppressor design that worked on a revolver platform. It either used a Ruger or a S&W 66 (dont remember) as its platform, but it had a shroud that completely enclosed the cylinder. Even then it still didn't work as well as an auto.
BTW.. Florida isn't just NFA friendly.. THEY'RE MAGICAL! ITS THE BEST DAMN STATE TO LIVE IN!! BAR NONE.. They have THE MOST LAX firearms laws of ANY STATE in the union. Seriously... Its an Awesome state!

Okay, it's well established that suppressing a revolver is kind of pointless, but just for arguments sake, could you use a 9mm can for a .38/357 if you keep the pressure down? Like for a levergun using .38 spl, or are the tolerances just too tight?

I have personally seen sub-sonic .357 & .38spcl shot through an AAC-Evo 9mm can. The powder and casing size does not matter as long as the bullet OD (outside diameter) is less that the suppressor's ID (Internal-Dia.). You can shoot 9mm on down from a 9mm can. That is why most people who shoot full auto .22's use .223/5.56 suppressors.
The only time a powder charge does come into play is when the pressure charge is going to be greater than the cartridge the suppressor was innitially designed for. IE shooting full house 357mag out of a 9mm can or .17HMR out of a .22LR. You will BLOW-UP YOUR CAN (eventually)!!!! Load your .357 to 9mm specs.. you'll be ok.
