Pistol silencer question

[sigstroker]

Some of the threaded muzzle pistol barrels I got have an o-ring, I guess to help keep the thread protector on. Some of them do not. I've shot my pistol with the one that didn't come with an o-ring, and the silencer tends to unscrew itself pretty quickly. Like in one magazine.

Those of you who have shot your silenced pistols much, do you use the o-ring with the silencer, or do you take it off? I wouldn't think it's any kind of issue with concentricity because the threads are still there. The o-ring sure seems like it would keep the can tighter, longer, assuming it doesn't melt.

I used to run an o-ring on my pistol barrels and it did help but my suppressor still loosened up. Now I run Griffin Armament’s CAM-LOK system and even when I have run my handguns hard my suppressors have not walked loose.

Suppressor twist on and off easily on 1/4 turn so no need to screw on/off and the 3-lug with taper adapter keeps it from walking loose. Another benefit with the CAM-LOK system is you no longer need to carry around different pitch pistons to change out for different pitched hosts. Before when I was shooting my 1911 in 45 (.578x28) if I wanted to use the same can on a 9mm (1/2x28) I had to change the piston. Then if I wanted to then use the same can on one of my Sigs I had to change the piston again because of the Sigs M13.5x1L thread. With the CAM-LOK you put a special piston in your suppressors (each unique to the can) and then a universal 3-lug style adapter onto the barrel.

With that setup I can run the same suppressor on different hosts without needing to change the piston. It’s revolutionary and I highly recommend it! Sure you have to buy adapters for each barrel and new pistons for your suppressors but the fact that they don’t walk off brings me peace of mind knowing my NFA item will not be damaged. Check it out on YT and see.

Good info mac thanks!

I considered it when it first came out, but I have so many different pistols that I probably wouldn't put very many rounds through, it seemed like it wasn't a good fit for me.

I was surprised how dirty the piston and spring got. With factory jacketed ammo, the piston and spring got gunked up after only about 50-60 rounds.

Sig,
My pistons for my pistol caliber suppressor has an oring inside the piston/neilson device threads so that it helps keep it screwed on. If I had any pistols with an oring as part of the barrel threads, I would have to remove it because my pistons have one already. If my suppressor didn’t, I’d leave it on the gun. All that said, I always have a mechanics gloves suppressor hot pad with me and check that it’s tight after every magazine. My .22 suppressor is threads only with no oring, so that one I really need to check after every magazine so I don’t get a baffle strike if it walks loose.

My SilencerCo/Blackhawk! pistons didn't come with o-rings, so I guess I'll try the one on the barrel.

Thanks

I expect that from a .22 can, did not expect so much fowling from .45. It was Federal Premium ammo too, not the cheap stuff. I'm not even sure where my tumbler is.

Did I really say "fowling"? Oh well.

Would a regular vibratory tumbler work? It would be okay if it just took longer.

BTW you don't want to use it on aluminum baffles. That's why I chose the .22 can that I did - stainless baffles.

Not sure what suppressors are made from, but if it is aluminum, ultrasonic cleaner might be a bad idea.

Took a Kaw Valley Muzzle brake that was aluminum to the ultrasonic, and almost ate the aluminum. The finish was there, but the metal gotten brittle.

This one in the photo is 100% stainless steel. Tube, baffles, and end cap. MFR recommends ultrasonic cleaning for this particular can. Great point about ultrasonics and aluminum though. [emoji106]

Silencer Shop did an article on that a few years ago. You should be able to just do it in your back yard, right? I guess a tiny bit of lead would come off, but the soda should be harmless(?)
