Threaded barrel issues

So I have a 92FS I decided to use as a host for my first silencer. I got a SWR Octane 9 HD2, and the threaded barrel from Tornado Tech. Well I just got a flash hider to play around with in the mean time and it came with an o-ring, if I screw the flash hider till it stops againt the threads it is pushing the slide back slightly and I worry about shooting it. When I put the o-ring on it has a tiny tiny sliver of light between it and the slide but it backs off when hand cycling the slide so I am not so sure this will work, can I dab some loc-tite on the threads and be ok? Or my thought was machine/shave some material because there is a bit of a bevel and some space before the threads on the flash hider start, so if I remove some metal from it it should stop and lock on the threads and not hit the slide?

Then my next concern is the mount on the can, I wonder if the threads will be far enough out toward the end of the mount to not be touching the slide. Anyone have this problem and how did they fix it?

For the flash hider I was thinking about removing some material.

For the silencer if it has interference I could swap to a Centurion slide and keep the full length barrel and have some more space there...

A couple of questions:

1) Are you using a piston with spring booster rear end for the Octane 9HD2?

2) If so ... is the slide being depressed by the silver piston of the suppressor?

As I do not have a 92, is hard for me to visualize how it is possible for the booster piston to interfere with the slide. If you are trying to use a fixed mount I can see how that might happen ... but I don't think you should be using a fixed mount with that pistol.

Sounds like tornado tech screwed the thread job up to me.

[Delasangre4231]

See the huge bevel before the threads start, I think that's my problem. Oh and sorry for the confusion, I don't have my silencer yet, I am waiting on the tax stamp. This is just worrying for when I get it, is this going to work.




Look at the little bit of the recoil rod sticking out showing that its definitely holding the slide from fully closing.

Take that silly flash hider off and use a thread protector like everybody else.

Tornado Tech are not new to the game so until you have your can in hand and can try it, there is no accurate way to guess whether it will work properly or not.

[Delasangre4231]

I just thought it would be fun, it also turns out it could double as a comp weight. But I guess I will stick to my thread protector.

[eastern_hunter]

The slide should not contact the device threaded on to the barrel. Any such contact will result in the slide not closing properly. Even a small contact can result in the barrel breaking at the threads. Looks as if the threads do go too far down the barrel.

You won't be able to tell exactly what the fit looks like until you have the can with the booster installed. If there is insufficient clearance on there on my pistol, I would probably mill just enough off of the front surface of the slide to allow two sheets of paper to fit between the nose of the slide and any device mounted on the threaded barrel. But I have a mill.

[Delasangre4231]

Ok thanks for the milling advise. I guess I will break in the barrel and wait for my can. I have been planning to get an extra slide anyways so one can be milled for the can and the other not.

I have a flat stone used for sharpening knives. I think this would work if you don't have a mill.

[Delasangre4231]

I have friend with a mill if I can catch him off work. But I may just go to a local gunsmith, I think I know someone with a mill.

I've got a factory threaded barrel for the 92 . . . whats your OAL?

[Delasangre4231]

How is a Factory threaded barrel different than mine? Forgive me if I am just having a brain fart but OAL?

[Broken11B]

OAL = Overall length.

There could be slight differences in a factory threaded barrel vs an aftermarket make.

[Delasangre4231]

Its the same length as my factory unthreaded barrel.

[Kramer]

Going by the bottom picture, it looks like the threaded section is too long and it looks flush with the end of the slide.

The threaded Beretta 92 barrel that I got last month from Gemtech has a little shorter threaded section and the barrel protrudes from the front of the slide.

[Delasangre4231]

You got one from Gemtech? Pictures?

[seattlite]

I don think the my 92FS threaded barrel is factory, but here are some pics:

[Delasangre4231]

Interesting, that looks to be actually extended a bit not just a normal length barrel thats threaded. I will wait and see how my silencer fits when I get it 6 months from now and if I need a different barrel then I will get one. Thanks for the pics.

[seattlite]

Hmm....you are right...never compared both side by side until now. Factory on the top. Anyone know the maker of the threaded barrel:

[redtazdog]

Modify the booster not the slide.
Most of the boosters extend away from the shoulder of the can
and OD of the booster can be turned to the same profile as the barrel
so then the can won't hit the slide.
But of course wait to you get your can to test it first then modify if needed.
Chances are if that flash hider is not hitting the slide then your can may not hit.
