Stealthy two ways: quiet AND concealable!

June 9, 2010, 10:56 PM
Just wanted to show off a crappy picture of my "compact suppressed" rig. Thompson Machine Poseidon on a S&W M&P9C host.
Now I gotta learn how to make kydex holsters... I could easily carry this concealed if I had a proper holster.

Just make sure you can pack a suppressed pistol with your CHL. Here in Colorado CCW of NFA items is verboten ... mostly that's aimed at SBRs and SBSs but unfortunately suppressors fall under the same rule here :(

But yeah, with the right leather (or Kydex) that would be cool.

I am not sure that adding 3-4" to the length of the gun keeps it in the category of "quite concealable" per se. I mean, I can conceal my shotgun under a coat as well and I have a buddy who has carried is S&W .500 revolver concealed (just to show he could) and it was a huge sucker.

Still, nice rig.

Who makes a threaded barrel for my full size M&P9?

What do you think of the Thompson Machine Poseidon?

How are the wipes? How long do they last?

Wow, that is tiny. How does it sound?

Hey brother,

Ive seen your setup on Silencertalk(fireman1291 here) nice rig.

To answer waterhouse, with wipes in place and 5cc-8cc gel or water it should last approx 20shots with FMJ 147grn ammo and sound like a bbgun. The wipes will be increasingly worn out shot after shot and the gun will get louder, until you change the wipes.

Interesting. Here in AZ anything lawfully owned can be carried, so you would be legal. I didn't think suppressors were getting that small.

The last year or so has seen a surge of development in smaller suppressor technology, particularly in 9mm and .22 cans. I think this is primarily due to the sound reduction of these suppressors has reached such incredible performance as to make building quieter suppressors very difficult and not particularly useful. The gunshot in a good .22 can with subsonic ammo is less than the noise of the action or bullet flight, and 9mm performance is very nearly as good. To build "a better mousetrap" now requires something other than noise reduction, like durability, minimal POI shift, or compact size. Several companies like Thompson and DeGroat have revived "old school" tech like wipes, once necessary to achieve adequate noise reduction, are now being used to get "plenty quiet enough" noise reduction in very small platforms. Progress is cool! :cool:

Here's another, Thompson Machine's Wasp suppressor with a Beretta 21A host...
(I promise I don't work for Thompson, I just really dig their stuff). I love this rig. It fits in a jacket pocket, and even dry it's quiet enough to not sound anything like a gunshot. Wet, it's almost as quiet as my bigger 22 cans.

Does the laser clear the can?

That's awesome... ! know if RI allows them during CCW?

How much of a decibel reduction are we talking about?

Highorder, I think stormlake makes the threaded barrels. order cheaper from brownells or any distributor.

Thanks for the info!

The review is free to anyone registered (even non-paying members) with the site.

Fired wet, with subsonic ammo, the Poseidon was hear-safe according to a meter 15 cm from the shooter's ear.

any chance you can do a youtube vid on this? I'm pretty sure I'm not the only one to see how quiet this shoots.

Does anyone have an address on Thompson Machine? I will be in Florida soon and would like to drop by to see their products if it is on my route.

Went to the site. It does not say where. No reply to e-mail either.
