O.K. I am getting a Form 1 suppressor but the threaded barrels kind of have me confused?
Its for a .45 and the ones I looked at say "gunsmith fitting required." What the hay is that?
I have a few full size .45s and don't want the hassle of having it fit. Are their .45 threaded that just drop in?
Thank you in advance. Tim from the swamps.

Are you talking about a 1911?

Link to company selling suppressors?

Could call and ask what pitch the thread is.

Ring threaded one pitch on outside another on inside done by pipe fitter sounds like a solution to explore.

Don’t listen to me though I’ve heard I paint in

My MAC 10 has a threaded barrel, heck I even have a fake suppressor on so I can hold on to it...impressive as shit for those who don't know any different.

Thread pitches are kind of standardized per caliber. Then you have inch or metric threads too. I have a metric threaded can on my H&K USP.

Very few barrel get the inside threads. The main reason for inside threads are the slide & barrel, or barrels are just not available long enough to thread. My H&K P9S would use an inside the barrel thread.

They had one in the movie To Live & Die In LA.

And then there are the suppressors that do not need a Nielson Device/recoil booster. Mac 10's and my H&K MP5k do not need the device. Most semi auto pistols need the device to operat the gun properly.

O.K. stay with me now I am learning as I go.

How a Silencer Pistol Booster Works

O.K. best I can figure here boon is that if your weapon has a 'fixed' to the actual lower frame barrel you do not need a booster?
Weapons that the barrels pitch up when fired must have the shock absorber booster or they will not work as demonstrated in the video.
Guess that is why we see a spacer in most of the suppressors for room for the booster?
But I am still wondering what the hay 'fitting required' is on these threaded barrels. I don't think? its the threads their talking about is it??

belt-fed · 07-14-2019, 11:54 PM

I think what they are saying the threads on the can need too be the same as on the barrel
but you got it about the booster

A vey big thing with threading barrels are that the threads are concentric. If not you going to damage the baffles or destroy the suppressor

Plus I just read them saying do not use a crush washer when installing as it can throw the suppressor out of alignment and damage it when fired.
This is more complicated than I thought.

Sometimes you need a different barrel link to get the timing right. I’v Had to do it a few times.

What did that entail hangfire? Did a machinist have to re-mill the threads?

baboon · 07-15-2019, 12:25 PM

The best you can hope for is ear safe with most suppressors. My intregally suppressed Ruger 77/22 is the quietest of all my suppressors. You hear the firing pin strike then either a impact or ricochet. I have a Quicksilver in 5.56 that does little for muzzle flash but makes it ear safe.

Suppressors are not the stuff of Hollyweird.
