Suppressing a Glock 19

[md8232]

I’ve purchased a KKM threaded barrel, and I’m beginning my research into various suppressors.
Problem is I don’t know what I don’t know.
For example, Nielsen Devices. Do I need one with a Glock? Any downside to one if needed?
Ablative material. Didn’t know what it was til yesterday. Good idea, or a mess waiting to happen?
I like the Thompson Machine Poseidon 9mm. Then I discover the Feds want me to return it every time it needs
a new wipe.
I want something small & light. Not interested in a multi caliber can.
OK, fill my head with knowledge!

Gemtech GM9.

User serviceable, direct thread onto any barrel (pistol or rifle), works for .22 as well.

Do you have any other cans, or friends with cans? If so, it's a great idea to try before you buy.

I am fond of the SilencerCo Octane 9K, having recently shot one on a buddy's Glock 19.

No. I'm on my own for this.
Looking for the Octane 9K, I found the Omega 9K. This is smaller and lighter, tho a bit fatter & louder.
I'm going to follow up on the Omega as I value size & weight the most.

We really need a "What you don't know about suppressors and why what features matter (or in most cases, doesn't matter)" sticky. Or maybe just a simple "how to buy any firearm or accessory using the 'mission drives the gear' decision making" sticky?

1) If you do not have a fixed barrel, you need an inertia device.
2) A suppressed pistol has a very limited range of practical applications.
3) Every company claims their product is lighter, smaller, greater sound and signature reduction, and/or "better" than their competitors.
4) They are all full of shit.
5) Most suppressor purchasers don't know how/why to prioritize features and capabilities. (Including agency and organizational purchasers)
6) Most people providing suppressor related advice are no more qualified to answer than the person asking.
7) Just about every commercially manufactured suppressor will produce negligible differences in practical performance.
8) Suppressors are not magic.
9) Pistol Suppressors are little more than tactical toys.
10) Suppressors don't add inches to your dick.

Good stuff, Sean. Given the realistic realm of uses for pistol suppressors, are there certain features you would prioritize getting (or, features that are much hyped but mostly meaningless?)

10) Suppressors don't add inches to your dick.

Unless your dick is threaded 1/2x28. In which case you need all the help you can get.

Decibels of reduction is one particular feature I put zero emphasis on.

Here is the problem with sound reduction claims: THERE IS NO INDUSTRY STANDARD FOR MEASURING SOUND SUPPRESSION LEVELS. Any manufacturer can claim whatever they want. But just because they claim it, doesn't make it so.

Attachment method is another. I struggle to find a practical need for QD features on any Suppressor, let alone a pistol suppressor.

Since it is relevant based on the OPs initial post; multi-caliber capability. There are only so many bullet sizes. Pressures and construction materials dictate more of a suppressor's ability to handle multiple calibers than simple size of the hole or the threads. I can't see a good reason to not leave as many options available as possible. The price difference between multi-caliber capable Suppressors and those that are a one caliber pony is negligible to the point of irrelevant, so why someone would consciously elect to limit the scope of usability is lost on me.

Finally...... I don't recall you being so judgmental LOKNLOAD........ not all of us were born with 5/8x24 threads.

I am probably going to regret answering this thread, as I am dating myself. Sean is unfortunately quite correct on sound measurements and multi caliber cans. I say unfortunate because, it wasn't always that way. There used to be an industry standard. It was actually the Mil-Standard and very few of us had the proper calibrated equipment and actually published the results. At the time(late 80'-early 90's) we also specified if a can was dry or wet, especially with dB ratings. Gemtech, Knights, SWR, AWC(didn't always differentiate wet and dry #'s in advertising) all had the correct metering systems. Two authors I know of also had the correct meter/mic combos.

With the push for user serviceable cans came a problem, a ligh level of customers couldn't put them back together correctly, causing lots of fucked up units. Mono-core technology is really nothing new, it was tried quite a bit back in the day(HK used it in the MP5SD) Problem was, it sucked and pretty much still does. You see some amazing feats of machining and design, but most don't come close the the potential of a can with conical baffles(designs vary). Bowing to the pressure of the marketplace, manufacturers gave customers what they thought they wanted and the industry stopped bothering with meaningful numbers. I am still quite involved in the background of the industry and it is amazing how many mono-core designs actually perform not much better than if the can is empty. Sad statement. Some of us older designers ahve to bite our lips quite a bit, trying to not sound like the old bitter bastards that we are.
As for Ablatives, well KY Jelly actually is the bomb when you are out at the range. Older type conical baffle cans will hold 3-5cc of water without leaking. Shooters Choice All weather(think they call it hitech grease now) grease works well injected into the rear expansion area. A test was done once with piss and it actually worked better than water. Smelled horribly though.
With the exception of the M92 and variants, you will need a booster device. On the M92, you can usually get away with up to 8oz hanging off the muzzle before you run into issues.
Just some ramblings from the old bitter bastard, hope they help ;-)

Welcome to the NFA world!

Yes, the Glock requires a Nielsen device, also called a booster. It helps the handgun function with additional weight of the silencer. Most, if not all, handgun silencers come with one. Fixed barreled handguns such as a Beretta 92, don’t require a booster but use a fixed barrel adapter.

Ablatives are messy. They do add a little more sound reduction and it doesn’t hurt to try.

For 9mm, I’m really impressed with AAC’s TiRant 9M. In the short configuration it weighs less than 8 ounces.

@JRCHolsters
Are there any user serviceable models that use a close to optimal baffle system that you know of?

I'm really good at LEGOs and stuff, and can put LEM pistols back together.

A decent can and a 1301 are about all that's on my definitely acquiring in the foreseeable future list, so this is relevant to my interests.
