looking for recommendations for mounting a supressor to a threaded p229 barrel. is there an gneeric adapter out there for a quick mount or is everyone doing direct mount?

Typically, a threaded pistol barrel mounts onto a Nielson device that is inside the suppressor.

Threaded barrel---> Nielson device captured by a spring within the suppressor.

US manufactured guns are right hand threads--SAE
European manufactured guns are left hand threads--Metric

Technically, there are two QD mounts from Griffin Armament for pistols. Cam-Lok and EZ-Lok. Cam-Lok is faster, but likely not as precise a seat. EZ-Lok is more precise than Cam-Lok, but slower to seat. Both are far faster/easier than 1/2x28, but you are still engaging with 1/2x28 or other barrel thread pitches. You'll need to buy the corresponding Griffin piston for whichever suppressor you have as well. Most people see it as a solution for a non-existent problem. I hate how long it takes to thread on 9mm and .45 direct mount, so I bought in, but I have not used my suppressors with it yet.

One other advantage is you can buy the barrel adapters for multiple different thread pitches and still maintain the same piston in the suppressor. For example my Glock 21 and my USP 45 have different barrel threads, but the Piston in my Rugged Obsidian 45 engages with the Griffen EZ-Lok on either. Now I don't need two different Pistons to fire the Glock 21 or the USP 45. I can put one on the other as desired without removing the piston. At least that's the goal.

Is it a factory Sig threaded barrel? Those are reverse thread metric, not the US standard 1/2x28, so pay attention to that.

I tried out the Griffin EZ LOK for a bit with my Ecco Machine can and while it locks up quickly and doesn’t walk off, it is also a bitch to remove once it gets hot. If you want to move your can around to different hosts, it means waiting far longer for the mount to cool down than one would expect before you can actually get it off the gun. Thankfully, it was a loaner from a friend. I’ve decided to make do with plumber’s tape and 1/2x28 threads with standard boosters.

Perhaps Griffin Armament should call all their systems "Quick Attach" rather than "Quick Disconnect".

yea its an oem sig barrel with the m13.5x1mm lh threads. I was looking at the Griffin mounts. It looks like I would have to take the mount off if I wanted to remove the barrel.I was hoping there might be another option. I'm running the SilencerCo ASR mount on my MPX and love it. I was hoping I could use something similar.

I don’t think what you want is available. The GA Cam-lok/EZ-lok muzzle devices are larger than that barrel opening in the front of slide, so would have to be removed if you want to pull the barrel. That’s not an issue for a PCC like a MPX, where the barrel doesn’t move, plus it’s surrounded by a roomy handguard.

SiCo is coming out with the S98, which looks like it might have a small QD muzzle device, but right now it seems to be 1/2 x 28 only.

I got a SilencerCo Spectre 9 to go on a P226 with a LH metric threaded barrel. The back end of the can is threaded "Alpha." It comes with a Nielsen device/"booster" to run on semi-auto pistols. It does not come with a threaded piston so I started down the adapter road: LH threaded metric piston. RH threaded piston for all my other pistols. Fixed barrel spacer to run it direct thread on a MP5 clone. Then today I decided the MP5 clone deserved a 3-lug mount.

They sell an ASR mount for it. The Spectre 9 is rated both subs and supers for 300 Blackout but I have another can for that. You can't hot swap these mounts, it is not instant, but as you can see, the can will fit on nearly anything. I think I know what this will eventually lead to for me is a 2nd Spectre 9, or a 2nd can with alpha threads that all this hardware fits on.

If I were to do it over again, I might have sold the LH barrel from the start, skipped the LH piston, and bought a RH aftermarket threaded P226 barrel. It would make swapping between pistols much easier. Good news is, if I buy an H&K pistol in the future I'll be set.

At least I bought 2 SiCo cans during the $200 credit last fall so I got 2 threaded pistol barrels, and the fixed barrel spacer in the credit. Oh yeah, and I got free a SiCo t-shirt out of the deal

There are other cans that are as versatile but I'm happy with the sound suppression especially compared to the weight ratio for this setup.

Every major suppressor manufacturer offers their handgun product with a 13.5x1 thread pitch option. This is the industry standard for 9MM pistols over in Europe.



I have used suppressed firearms for many decades even though I have only owned my own for 20+ years so far. I have never come across a situation where a quick connect or disconnect would be beneficial.

I admit when QD mounts started to become a thing, many of us were worried about misalignment and baffle strikes. It was a very rare occurrence and the industry has pretty much resolved the problem

My only firearms with a quick disconnect attachment are my MP5s. Since I put the suppressor on the firearm before we start shooting and do not take it off until we are home, I do not see the need for the quick disconnect. It is just extra money



All of my SIGs and HKs left the Factories with metric threaded barrels

Man, I learn something here just about every day.

Where is the right place to fine one of those?

Oh, wait. I think I found one.

Yeah, Silencerco makes a number of 1/2x28 threaded barrels for guns that typically have funky thread pitches. When I have the budget to throw at it, I'll be picking up a SiCo P226 barrel as well.

I don't think thread pitch makes a difference in the OP's issue. I don't see how its possible to have a qd so minimal in diameter to allow barrel removal without removing it. I looked at a zillion picture of the S98 thing Dwill104 posted and its not definative to me, and I can't find any specs with the diameter. But I'm betting against it.

100% the Griffin has to be removed to disassemble the slide. There’s a torque spec for it and they say not to use thread locker, obviously. It was another reason I decided not to go with that system.

It would be nice if a manufacturer developed an open source very course/taper mount similar to EZ-Lok/Cam-Lok designed to be no larger in diameter than thickness of the majority of pistol barrels. Then sold pistol barrels + Pistons to retrofit into existing suppressors. A man can dream. Or, better yet, have mainstream manufacturers produce integrally suppressed pistols, a la Maxim 9, but for the average Joe. Ie reliable and available.

For my 229 I'm good w/reverse threads. I also have a no thread/no quick detatch 9mm too.
