I'm basically at the point now where I have most of the weapons that I want. I'm thinking that the next thing I would like to get is a 9mm suppressor that I could use on both my G26 and Beretta 92. I've been looking at the AAC suppressors and they seem to be the best deal. I know I can get a sign off from my CLEO, so that won't be an issue. I intend to use it for home defense and for target shooting.

Here are a couple of my concerns:

*I know suppressors work best with sub-sonic ammo. Unfortunately, 9mm subsonic costs a bit more than regular super-sonic ammo. Do suppressors still significantly reduce the sound signature with super-sonic ammo? I'm not looking for movie quiet, I just want "not deafening".

*How much does ultrasonic cleaning cost? Can't I just clean the thing with Dawn and run tap-water through it? I don't want to spend a ton of money on cleaning.

*Threads. Are most 9mm suppressors 1/2x28 LH?
 
I think you still get the crack but not the boom. Not sure why you wouldn't just disassemble it and use soap and water with a oil wipe finish.

But I don't own one so I may be way off base.

147 grainers will stay subsonic in a quite long barrel (7-10"), so I wouldn't be suprised if the lighter bullets stayed subsonic in the short G26 barrel.

Either way, a can quiets things down a LOT.
 
AAC is suing a guy, basically because he posted that he didn't like their stuff on another forum. Take that how you will.

I believe that most cans on the market other than the ones intended for .22 long rifle are factory sealed. From what I understand, most people use an ultrasonic tank to clean them.

Any decent can will eliminate the crack when the gun is fired, however, when/if the bullet passes a stationary object downrange you will hear the supersonic crack. You'll never get "movie quiet" because it's simply impossible.

I can't remember what they're called, but your guns may require a can with a built in recoil booster, or a seperate one in order for them to cycle properly.

If you haven't already shot suppressor equipped guns, there is a good chance you could do so via the various gun forums on the net. There is a group of shooters from around the D/FW area that do shoots up near me every few months, and another couple of groups for south, east, and west texas. They bring out everything from standard firearms to suppressed full autos. The last one I went to had one guy with an M60!!!! and several other folks with other FA toys. IIRC, a suppressor dealer was at one of them, and a local suppressor manufacturer was at another.
 
Isn't just about any 147gr standard pressure 9mm going to be subsonic?

I think 1/2-28 is the standard thread for .22 bores. They use something else for 9mm to avoid getting an undersized muzzle device on a gun and doing very bad things (tm) .

Just buy subsonic, most comes in the form of 147gr. I mostly use American Eagle 147gr flat points or Winchester 147 JHPs. Fiocchi 147 is the exception, I think it is too fast. Using non-subsonic ammo with a 9mm can is pointless, no it is not as loud as it would be without the can, but it is much louder than when you use subsonic.

Don't worry about cleaning, I am only familiar with the Evo9, but I spray it out with WD40 and soak it in mineral spirits and it works well enough to clean it, and doesn't harm the finish.

*Threads. Are most 9mm suppressors 1/2x28 LH?

I think it is 1/2X28 RH, and this what will be easiest to find a Lone Wolf Threaded Glock Barrel in. Factory Sig & H&K is 13.5X1LH. If you buy the Evo9 you can buy another piston so you can easily change the can's threading to suit the pistol you are shooting.

The AAC Evo9 is a great can, it has a 'booster' built in so you don't need a separate LID, booster whatever you want to call it. You should also check out the swr trident 9 which I hear is also nice.
 
I have a Gemtech suppressor. Their instructions specifically say not to clean it, and if you do it voids any warranty and can ruin it. Some fouling actually helps. If it gets too dirty, it can be returned to the factory to be rebuilt.
 
Before you buy anything!!

Take a look at Bryon's website www.major-malfunction.com

You will most likely save $50-$200, depending on the model you're looking at.

*I know suppressors work best with sub-sonic ammo. Unfortunately, 9mm subsonic costs a bit more than regular super-sonic ammo. Do suppressors still significantly reduce the sound signature with super-sonic ammo? I'm not looking for movie quiet, I just want "not deafening".

Yes, the muzzle blast is greatly reduced - you turn it into a .22lr in terms of noise. SHOCKINGLY quiet when you run subsonics, though.

*How much does ultrasonic cleaning cost? Can't I just clean the thing with Dawn and run tap-water through it? I don't want to spend a ton of money on cleaning.

Depending on the model, soap/water or a solvent is what the cleaning procedure is. Generally, though, centerfire silencers having jacketed bullets shot through them don't get very dirty.

*Threads. Are most 9mm suppressors 1/2x28 LH?

It depends. Most threads on BARRELS are 1/2x28 RH (not LH) for 9mm, though many manufacturers have options available.

They're suing him for stating over and over that he had inside information that a company dropped AAC from a contract to provide silencers - and he said this over and over without any proof. That's not legal to do, so he called them on it. :)
 
So any ammo listed as less than 1129 ft/sec. would be sub-sonic, right? That's the speed of sound according to Wikipedia.

Like reducing the echo in a tunnel by piling dirt inside of it? :)

Current production, or ever?

Do realize that small = LOUD as far as 9mm silencers go.

STW makes one about 4" long, you'll have to e-mail and ask about it.
AAC used to make the Spider (5.5") and Scorpion (4") silencers.
AWC makes the Abraxas (5.7")

All MUST be fired wet to have even close to acceptable results.

I really would just get a "full size" silencer for the money, you'd be happier.

Most people stick to 1000 ft/sec, as ammo loads have a variance and it is annoying to get a round that goes trans sonic.

Do not put an aluminum can in an ultrasonic tank, you'll screw it up pretty badly. Use those on steel cans only.

Also, small 9mm cans are loud as hell. Older designs like AWC, or Gemtech's trinity are loud as hell too.

I'd get an AAC evo9 or SWR Trident.

i have the trident on a USP9 and love it. very little FRP. MOST all 9mm cans cannot be disassembled by the user for cleaning due to the fact they are a "sealed" can.
 
I have an AAC .223 Ranger.
I bought IMI blue tip sub sonic ammo and I can't tell the difference between this and regular by plain hearing.

When firing the can on an AR with my head rested on the stock I can hear the recoil of the buffer spring over the report of the muzzle.

I also use it on .22LR and it sounds like a pellet gun with hyper velocity .22 ammo. When I use sub sonic .22 ammo, the muzzel report is not distiguishable again with the normal ear.
 
PTK beat me to it. Check with major-malfunction, he has the best prices I've found and is truly a good guy to deal with.

Your questions:
*Do suppressors still significantly reduce the sound signature with super-sonic ammo? I'm not looking for movie quiet, I just want "not deafening". Here's my explanation: Shooting a .556 AR without a can, and wearing muffs; is still pretty darn loud. Shooting the same gun with a good can? I don't even wear muffs. You still hear the crack, but it is substantially quieter. You'll never get movie quiet.

*How much does ultrasonic cleaning cost? Can't I just clean the thing with Dawn and run tap-water through it? When you're researching suppressors, check with the individual companies. Several different materials can be used (anywhere from Stainless Steel to carbon fiber), some require ultrasonic, others you can tear down and clean as you wish. Almost any auto shop with an ultrasonic parts cleaner could probably run your can for $10-$20.

*Threads. Are most 9mm suppressors 1/2x28 LH? Sorry, no help on this one!

Make sure you buy a suppressor with a built in booster. Make sure you buy lots of 9mm ammo, because you will shoot it more than you ever thought possible :)

As for AAC... search over on ARF. I don't care about the who, what or why; but when someone from a company posts on a public forum in an unprofessional way... well long story short I prefer YHM or Gemtech.

Gunkid's in jail, campers...

The stuff Gunkid did on the internet had no bearing on his arrest and conviction. All it did was increase the exposure of his stupidity because so many of us knew who he was. He went to jail because he was a convicted felon in possession of firearms and his wife (ex?) turned him in for stealing from her.

They reduce the noise from "you must have hearing protection" to "you should have hearing protection".

With 9mm so easy to make subsonic, there's not much reason not to choose "Hollywood quiet" over "still dang loud".

AAC is good people. If they're suing someone, it's probably deserved.
You can go ask 'em yourself (and get lots of other suppressor questions answered) over at http://www.silencertalk.com

If you haven't already shot suppressor equipped guns, there is a good chance you could do so via the various gun forums on the net.

AAC sponsors the biggest silencer-only shoot annually in NE GA. Details here.
 
Another question:

I was told that the European standard thread, M13 5x1mm LH is better than the western 1/2x28 because it is a left-handed thread and thus, the exiting bullets will tighten the barrel (they spin the same direction as the threads). Is this correct? I'm guessing if the Germans use it as a standard, they probably have a reason for it.
 
I have a barrel threaded in 13.5 x1 lefty. It is ok, but it can still unscrew if you are not careful. Standard protocol is to check and tighten it at the end of every mag.

I think the tightness of the threads has more to do with them unscrewing.

The only reason I'd visit AAC's shill site is to get ideas from the membership on building my own. ;)

Besides, there's a local(to me) SOT that builds suppressors that I'd rather give first dibs to on a sale.
 
I almost bought an AAC until I found out how much they like to sling mud at their competition. I bought a Gemtech Piranha (.223) instead. Although I am still waiting for atf to allow me to have it.
 
MAC-11/9 w/Lage Upper & GemTech Viper Suppressor

Here's what 9mm subsonics sound like, and these are out of a M11/9 open bolt which isn't known for it's stealth. These are Georgia Arms 147 gr. FMC @ 950 FPS. I own 2 AAC cans in different calibers and will buy probably end up getting an Evo-9 for other hosts since it's not FA rated. I try to purchase the best solution for the application and don't let people with agendas influence my decisions.
