Having a Problem with my Suppressor > Silencers

Posted: 5/29/2008 11:35:30 AM EDT

About 2 months ago I bought a AAC Evo 9 for my Glock 17 and Glock 19. I bought LW threaded barrels for both of them and both work great. The problem I am having is that the suppressor comes loose after about 5-8 rds. I have tried Teflon tape and the suppressor still unscrews itself. Is there any remedy to this, like a QD for a pistol barrel? Or is this something I am just going to have to live with. Any advice or help would be great.

Its pretty much a fact of life. I have the same problem on my G17 LWD barrel and Trident LCD. Did you just do 1 round of teflon tape? If so, might try a couple of rounds to make it a little more tight. Thats my $.02 worth. Maybe somebody else can chime in also.

Use a drop or two of purple low-strength Loctite. The only place I know to get it is from Brownells. It is a reusable type of Loctite that really just fills in any differences between the thread surfaces. I have been using it for years without applying any new drops. If you put too much you will have to get it pretty hot to break loose.

Or, buy a Jarvis or KKM barrel. I have no problem at all with these. I've used several from both companies. Buy once, cry once.

Just curious......Why would a barrel from Jarvis or KKM not allow the can to back off if they are all threaded with the same pitch

There are different classes/tolerances when threading even though the pitch will be the same.

I agree totally with this, I've never had a problem with my KKM barrel for my Glock 19 and Trident.

Thanks for the help. Looks like I might have to fork up some cash and get a different barrel.

Which barrels are better: Jarvis or KKM?

My evo45 fits perfectly with the KKm in my G21SF. I chose KKM because of the piss poor-we will get to you when we can-oh..you only want 1 barrel type of customer service that I got from jarvis. KKM was prompt friendly and I got it in a week, instead of dealing with jarvis' 4 month wait time. KKM is riciculously accurate. mine is done in .578x28 FYI.

I use a Danco #7 "O-Ring" from the Home Depot on my P22 with no baffle strikes or POI issues.

Of course, all suppressor manufacturers recommed against using O-Rings because they may lead to baffle strikes due to suppressor alignment issues.

Shooter beware

I have a LW barrel on my G17 and have not had any trouble with the suppressor loosening even after a whole afternoon of shooting. YMMV

+1 on the KKM Barrel, never had any problems with my G17, Trident combo.

I had the same problem with my Noveske-cut Glock 34 barrel with the standard 1/2x28 thread and my Evo 9. I spoke with John at Noveske's who sent some of the absolute thinnest O-rings--maybe 1/2 a millimeter--it fixed it.

This problem is shy I prefer the "European" threading of 13.5x1 LH--the can tightens rather than unscrewing....Never have the problem with my SIG226 or Jarvis Glock 26 which has this thread pitch.

Does your piston housing have the O-ring in it? I believe all the newer EVO9s have an O-ring, if it doesn't maybe contact them and see if they can send you one.
