Glocks and Silencers

1208 Views 12 Replies 9 Participants Last post by  -gunut-
Just out of curiousity: How well do glocks work with silencers? I have heard some "rumors" about them absolutely neither liking subsonic rounds (147gr) nor the weight of the silencer.

Second question: how to mount a silencer on a glock? Take a factory g34 barrel and have it treaded? (does Glock sell the barrels without the rest of the gun?)

Glock only sells factory threaded barrels to government/military.

For civilians, almost all rely on aftermarket threaded barrels.
Before someone else jumps on you, "suppressors". Especially with supersonic rounds (ie most of them), you aren't silencing anything.

And there are several companies who sell aftermarket barrels including Storm Lake, Lone Wolf, etc.

Make it worthwhile and go .45, or .50 GI even. Makes more sense than suppressing a 9 or .40.
Well, I will not be able to buy one as they are more or less illegal here in Austria. So, the question is purely academic: I'm just trying to learn more about things I will pobably never even see in reality.
I have a can for my 9mm glock. I haven't had any problem with it feeding 147 gr sub sonic ammo. The can works pretty good but it's not like hollywood. 9mm sub sonic is expensive to shoot if I were to do it again I would go with a 22 lr silencer. I bought a extended threaded barrel from lone wolf.
I have a Glock 17 with KKM 9mm barrel using SWR can. Shooting subsonic works fine and cycles the firearm. It is not "movie" quiet, nor can it be with the Glock style of cycling. Still, it is a LOT of fun to shoot.
Remember supersonic ammo bullet speed is not the major component of firearms noise. It is the gas expansion. Having a can on shooting supersonic will help reduce the noise. The supersonic crack will still be heard, but the noise will be reduced quiet a bit.

Suppressor is simply a more accurate term. When they first came out they were called silencers, so both can apply.

As for suppressing supersonic rounds, there is a vast improvment. It takes a firearm from not being hearing safe to being hearing safe. It will still brake the sound barrier, but it will do so down range away from the shooter. So you protect your ears and conceal the location of the shot.

Why does it make more sense suppressing a .45 over a 9mm? Both are great, but 9mm will be quieter with 147 gr. ammo.
Certain suppressors have been proven to work very well on Glocks for a long time now. For all guns with the Browning type of action (which a Glock has) you need a suppressor that has a special mechanism in it, to de-couple the mass of the suppressor from the gun barrel. There is also a spring loaded piston in there that actually pushes back on the barrel and helps it cycle properly. They are very different from what you'd mount on a gun like an Uzi, where the barrel is fixed to the frame and does not move down in the back end when it cycles.

Google the AAC Evolution series of suppressors, or look at these

and also look at the Gemtech brand to see some of them.

You can also hear some opinions from guys who own and shoot suppressors at www.silencertalk.com

Most of them over there will tell you that with pistols calibers, the smaller the bore, the better it will silence. 22 silences best, 9MM is still pretty loud, but good, .40 is louder, and .45 is louder yet, but still a lot quieter than an unsuppressed pistol.

My point wasn't to nitpick, but that someone else was likely to if he called them "silencers".

And are you saying a suppressed .45 will be quieter than a 9mm from experience? The supersonic crack won't happen down range...it'll happen at the muzzle. .45 = subsonic.

My understanding is that smaller calibers suppress better simply because the larger hole lets out more hot gasses/"noise". And if comparing standard ammo, a .45 does have an advantage in the sense that it is subsonic to start with. But that advantage is lost due to the size of the barrel.

Regardless of this, if its a choice of having a suppressor or not, its always going to be better to have it. The only time this does not apply is at the range or for recreational use. But for survival situations etc its a step closer to safety.

I said that 9mm 147 gr. 9mm is quieter suppressed than .45.

If you are using, say 115 gr., the .45 will overall probably have less noise.

147 gr. 9mm = subsonic .45 = subsonic

As for the supersonic crack, it happens in the barrel, which is suppressed with the can, and when it slows down and breaks the sound barrier down range. That is why it is still hearing safe but there will be a crack maybe 75-100m down range.
