surpressed Glock?

[Stoney]

Heard 2 guys at a LGS talking, one said you had to use special bullets and the other said, no you had to use a special spring to make it cycle, what's the story?

Re: surpressed Glock?

well of course you need to use subsonic ammo in any silenced firearm, if you want it to be quiet. 147 grain subsonic 9mm ammo, or larger, isn't exactly special, but it is different from the normal stuff most people buy. Which isn't to say that you can't use regular ammo, but of course it will make a lot of noise.

While I've never known anyone to need new springs, you do need a booster for the gun to cycle. Most modern suppressors have a booster built into the rear of the suppressor, but not all do. These are questions you need to research when you make a purchase.

Re: surpressed Glock?

I cannot speak for the Glock, but my 92F required a recoil spring change. I do not recall if it went lighter or heavier.

A 1911 requires a booster but we are not talking 1911.

Some 92s can get away without a booster, although like you the people who do that usually have to change springs. But just about every other brand that has a what some call a tilting barrel lockup require one. That includes Glocks, most H&Ks, Sigs, 1911s, etc... Guns with a pinned barrel like the Walther PPK don't need one because the barrel is stuck to the slide and only moves front to back.

Some people say that they can get away without a booster by shooting ammo that is powerful enough and heavy enough, like 158 grain 9mm. But I don't see why someone would go that route, when you could just buy a suppressor with a booster in the first place. I guess if you are switching between a pistol and a carbine a lot, which obviously has a fixed barrel, it might make some sense.

20) What are boosters and Nielsen Devices? 10/22/2012
Firearms utilizing the Browning tilting barrel design, during the cycle of operation, require that the barrel tilt upwards at the muzzle. The shorter the barrel, the more exaggerated the angle of the tilt. Putting weight on the muzzle end of the pistol is like adding weight to the end of a seesaw. The chamber end of the barrel locks into the slide and the weight of the silencer cams pressure upwards. When the pistol is fired with weight at the muzzle end, these types of handguns (including 1911s, Glocks, Sigs, M&Ps, and most popular brands/designs on the market) have trouble unlocking. If they do manage to successfully unlock, they will have trouble lifting the weight of the silencer and cycling properly.

A Nielson type device, like the Advanced Armament A.S.A.P. (Assured Semi-Auto Performance) system, assists the pistol and allows for reliable function. The A.S.A.P. system consists of an action spring and a piston that is threaded to mate up with the host weapon’s muzzle threads.

I have had no problems shooting my G19s suppressed, with or without subsonic ammo.

Re: surpressed Glock?

My 92FS cycles reliably with 147gr subsonic ammo just fine w/ no booster.

I made my 9mm suppressor as light as possible in hopes of it cycling w/o a booster on Sigs & others too but no joy. It will almost cycle on a P229 - unlocks, slide moves back, trigger resets, and goes back into battery. But the slide doesn't fully move rearward when cycling from the extra weight so the spent case is never ejected. It just re-chambers the spent casing & drop the hammer on it.

But the 92 is the primary host & the CX4 carbine is 2nd host so I didn't want a booster.

Both. Give it sub sonic ammo and it will shoot quietly canned.

Re: surpressed Glock?

I have LWD barrels in a 17 and 26 and use an AAC Eco-9 suppressor with them. I have never had an issue with any ammo Ive used, sub or supersonic. No spring changes, or any other changes necessary. Function has always been 100%.

They are quietest shooting subsonic with an ablative (I use water) in the can. Even "dry", with supersonic, they are still pretty quiet. Neither are "movie" quiet, but I can shoot them without ear protection, and my ears dont shut down. I dont even get an extra ring. At this point, a single .22 LR round will mute my hearing for a couple of days, so that will give you an idea as to how well the can works.

Re: surpressed Glock?

If you like to shoot wet, try wire pulling gel. You can get it at Lowe's or HD by the electrical construction stuff. Comes in a big bottle that's pretty much a lifetime supply & cheap. Just about a pea-sized drop spread on blast baffle will do ya - don't go nuts with it.

Re: surpressed Glock?

Only thing I changed on my G17 to shoot suppressed was the barrel.

Had to buy one that was threaded. went with the storm lake barrel.
