YHM Cobra suppressor on a Glock 19

[MAYNARD4507]

@austion66 file necessary paperwork with the BATFE and $200.00 tax stamp

[austion66]

what kind of legal hoops do you have to go through to get a supressor?

[Hartatttack420]

@austion66

None here in Missouri!

[shotgunstevie]

Forward it to 22s.

[naur115]

the last 5 rounds sounded like they were low power rounds.

[squidvis]

Damn those last 5 rounds were quiet... A lot of airsoft guns make more noise than that haha

[chadphilpott]

Is that a reload or a factory load? I would like the data if it is a reload.

[lhoppen]

oh my god....he turned it into a 22!!!

[blizzard249]

Anyone thats wondering why its not like in movies is because of 2 things: Its called a suppressor because it suppresses the gun. A silencer silences guns. Subsonic rounds sound silenced because they do not reach the speed of sound, and the others do making them suppressed.

[MrChondro]

@blizzard249 Thats the YHM Cobra 9mm..One of the loudest cans on the market..A silencer and a suppressor are the same thing..its a game in semantics..The BATFE and people that own them call them silencers..People that don't call them suppressors..Thats the only difference..9mm is right on the threshold of Supersonic..115 & 124 grain are moving around 1200 fps..Hence the supersonic crack..147's are moving about 1000 fps and don't break the sound barrier. 147's also have more kinetic energy.

[D3ADLYforce]

@MrChondro I own several of them and have never called them 'silencers'.

[an10nee]

Lol I like the saying at the end

[DuDaX]

Is this really even a silencer? Cause it didn't sound like one...

[samuraimax]

@DuDaX Are you basing that on the last time you watched [insert_generic_action_movie]?

[DuDaX]

@samuraimax Maybe.

[rotak98]

@DuDaX A 'silencer" technically doesnt exist. "Suppressors" just muffle a shot, nothing can make a gun as silent as some movies suggest.

[DuDaX]

@rotak98 I see, thanks for the info ;)

[TheDanstheman3453]

@rotak98 to bad too.

[Daytonaman675]

@rotak98 dear god please read the NFA of 1934 and the original patent by Hiram Maxim before you repeat that again.

[fryshakemeat]

@rotak98

That's not true.

The Mac 10 is extremely quiet with its suppressor.

Although its suppressor is huge.

[DobermanCrew]

@rotak98 except a pillow over the victims head ... and the gun pressed in to it while you shoot him or her in the head of course:)

[skurfer101]

Right on good representation of Super Sonic vs. Subsonic munitions through a suppressor.... Gemtech also makes an excellent product.

[ecollins92]

god tht sub-sonic gets me hard as a rock

[teddycanary]

If you want single fire, can you hold the action closed with your thumb? Some guys at the range were discussing it as they left to keep a shell from ejecting.

[WoodstaS]

@teddycanary Only if you won't be needing that thumb anytime soon...

[Katana9990]

cool! thanks for showing us what a difference it makes! good luck with any future vids...

[jar3351273]

thank for the imput on the diffrent loads

[jbeard82]

How much is the YHM for the 9mm?

[fatdan172501]

actually the first and proper term is silencer thats what the inventor dubbed it when it was first created but that term does not really describe its function vary well so the term suppressor was adopted and is now used and what i think is the proper term cuz it describes the function more accurately.

[stealthmarine83]

silencer is the incorrect term, they are actually called suppressors, the whole point of it is not to make it silent but to make it sound like something other than a gunshot

[guthywoodry]

Superb video, many thanks for you contribution.

Pay no attention to the hopeless imbeciles who comment on everything they don't know.

[thekickitin]

that does not sound silent

[FrostwolfV]

These aren't Hollywood suppressors, of course they're not silent.

[thekickitin]

they are silents. what the hell are u talking about? u can hear it

[FrostwolfV]

I mean that they aren't as silent as they are in the movies.

[thekickitin]

haha im not thinking of movies..... it is games

[shortround63]

@FrostwolfV That was pretty quiet when the rounds switched to subsonic.

[SaxonSwine]

Hollywood silencers sound louder to me, like "pew pew pew", when IRL it's more like "click click click".

[jbeard82]

@FrostwolfV to be honest its even louder than the video shows.

[onyxpilot]

My tax stamp took 2 months and 16 days to clear as of last week. I think they are pretty caught up to say the least at NFA

[windsor6699]

awesome suppression. i just got my yhm Mite .22 can in, only took 3 months to clear, i am so pleased with the quality, the 9mm cobra is for sure my next purchase after seeing this. thanks for posting.

[planchik]

i always thought that more grain the faster the bullet goes... can someone explain that to me what the grain means? thank you

[uclajd]

Grain is the unit of weight in ballistics, bullet weight, powder weight, etc.

1 ounce = 437.5 grains

115gn bullet = .263 ounces

147gn bullet = .336 ounces

Higher grain, slower bullet because it's heavier, assuming the powder charge is the same.

[planchik]

thank you for explaining that to me

[WALL45tech]

I thought the grain measurement referred to the weight of gun powder?

[uclajd]

It can to both, but in this case it is referring to bullet weight.

[xpaullettax]

i know this is off topic but what was that song

[dusty101011]

"Name of the Game" by The Crystal Method.

[xpaullettax]

thanks man

[hemi426bee69]

ATF is majorly back logged because everyone is catching on to the Revocable Living Trust. It was primarily designed for people who couldn't get signatures. That is what ATf told me when i called them and asked.

[msninfamous]

Very nice!

[joae1975]

Nice! How long did it take for you to get your silencer from the day the ATF cashed your $200 tax stamp? I heard they're super duper backlogged.

[Adammartini]

it will take about 6 months

[joae1975]

Since I posted that, I got one of them. The App was filed in 12/08, check cashed 4/09, silencer in my hand 10/09. So you're right. The guy said it might not take as long for the second one because I already jumped though the hoops once. My 2nd check was cashed 09/09, I'll let you know, if I can remember.

[rtrbrtsn89]

Great video, other than the first 20 seconds of fluff. That really was an amazing comparison though, it really illustrated the difference. Pretty much all you heard with the subsonic was the clicking of the action of the gun.

[arkangel8419]

sub sonic is def the wauy to go if u ever really need to pop sumone within earshot of the public

[rednoseroxy]

21 seconds of garbage, then a sub par suppression. This was garbage.

[MadeinHell2]

Darn. It really makes a difference. Without subsonic ammo its still pretty loud.

[MadeinHell2]

Ps. Can you use subsonic ammo without silencer? and if you can how does it sound then?

[shittyfuck]

will the suppressor reduce the power ?

[makarthamin]

not necessarily, but using an underpowered round (subsonic) like in the video enhances the sound reduction.

[dbmccart]

What will reduce the power is the Subsonic ammunition that you need to make it quiet.

[C6Jimmy]

What brand of barrel do you use?

[supercharged03]

I love this video and that gun/suppressor.

[insomniac4ever]

so were 2 different types of rounds fired?

[kyleChall]

Yea, the second set were subsonic rounds i believe, They do no create a loud crack sound because their velocity is typically below the sound barrier.

Less power, but less noise = P

[sevenedges]

no you don't have to change the spring, I have fired thousands of rounds through the Glock 17,19,26

both subsonic and non, it will still have enough energy to cycle the slide with the subs

[aodhanof90]

do you have to change the spring to make the Glock work with subsonic ammo?

thanks

Aidan K

[supermankicass]

That's still pretty loud.

[mbucari1]

The supersonics were pretty loud, but that can't be helped. But the subsonics were extremely quiet.

[crazyredlion4500]

Is it because the bullet weight is greater or do you use a different type of powder? Or is it both?

[PistoleroJesse]

No it's because the 115grn bullets are traveling faster than the speed of sound and the 147 are not.

Look at the wiki to see representative chart of bullet weight and velocity:

wikipedia(dot)org/wiki/9x19mm_­Parabellum

[crazyredlion4500]

I understand the bullet is traveling less than the speed of sound. The question is how is sub sonic achieved? by bullet weight or by using a different type of powder or a combination of the two?

[PistoleroJesse]

It's all pretty complicated, but to put it simply there are 3 factors: bullet weight, how fast the powder burns, and how much powder. Those will determine how fast the bullet comes out the barrel. Increase bullet weight with the same amount and kind of powder, you get a slower bullet, but with roughly the same kinetic energy. As long as the maximum pressure is not exceeded (34,084 psi), and the bullet still makes it out the barrel, you can pretty much load whatever you want safely.

[billdeal]

he answered your question, because you're too lazy to hit a link

[crazyredlion4500]

Was I asking you? No I was not. I am a reloader and I was just picking his brain for the heck of it. Honestly I am so sick of rude juvenile dickheads who have ruined message blog boards, chat rooms and sites like youtube who type before they think.

[billdeal]

oh, bravo. *claps*

[GrizzlyBears552]

Nice vid. Very informative. And good equipment; I could even hear the brass falling. Man what a difference. That sub-sonic is the sexiest thing I've heard all day.

[ogdencur000]

were the last five sub sonic rounds?

[vampov]

I'm going to guess yes. You can hear the sonic crack on the others.

[sibrent1]

why guess when you can read the intro to the video that clearly states subsonic rounds were used . . .

[papercut231719]

because the first few shots had a sonic boom; they weren't subsonic. maybe they were meant to be, but they weren't.

[cal63look]

Holy moly, those last five sounded like a BB gun!! Thats freakin awesome! Excellent Video!!!!!

[Glockman2619]

the subsonic are awsome!

[tjmilburn2007]

WOw; BIG different in the first 5 and the last 5.

[Hamcarver]

I am interested in how silencer/suppresors and ammo work. Is the subsonic ammo easily available, and is it less noisy if shot without the silencing device? -Thanks

[cha0scl0ud]

subsonic ammo is quiter to the trained ear, since it does not have a sonic "crack" - which is a mini sonic boom caused by higher-velocity (supersonic) ammo. With most rifles you will hear a characteristic crack, easily identifiable in a range with an echo. Most pistols (9mm, .45, etc.) just "pop" when fired if they are subsonic.

[heath8843]

supersonic ammunition makes a small sonic boom as cha0scl0ud said. the reason you must use subsonic ammo for a suppressor to function properly is because supersonic rounds Carrie on the sonic boom outside the suppressor, since subs don't have this boom, they can be suppressed.

[matty056]

that is awesome

[shitpickle1128]

nice

[SASL96]

dat is true what was the reason those last 5 rounds were much quieter

[zentanker]

already been answered, and it even says right at the bottom of the damn video!

which part of SUBSONIC AMMO do you not understand?

[dirtyminded604]

Why were the last five so much quiter?

[bimmers50e30]

sub sonic... its all about how fast the bullet is going.

thats why jets don't go super sonic above land. the noise of the airpressure (supersonic) is 10x louder than the noise of the engines. the B1-B bomber usally just flyes supersonic over then enemy and they just give up because its sooo loud that there heads hurt from the pressure wave. i'm told you can't even hear the engines, just the sonic wave

[CragarShinoda]

ACTUALLY, THE B1-B Lancer hardly ever flies at supersonic, though it is more than capibable. This would give away it's anti-radar "stealth" signature and leave it very much suceptable to detection.

[ChelseaLh14]

Wow. HUGE difference. Never tried it myself.

[K40Shooter]

Uh...no. Heavier bullets have more momentum and sectional density, and will generally penetrate further than light bullets. Simple physics 101, man. Light bullets are high velocity, and the JHP's open up faster and more violently, thus reducing penetration. The ONLY .45 ACP rounds that underpenetrate are the worthless 165 and 185 grain bullets. Nobody makes a 180 grain .45 ACP bullet. Almost ALL police use 124-147 grain in 9mm, due to 115 grain's inadequate penetration to reach vitals.

[supercharged03]

sub-sonic bullets rock.

[oconprop]

This video really is a perfect example of a good 9mm can. On my G19 with 147g ammo, it sounds like a brad nail gun. Put a little water, or ky jelly in the back of the can and it is even quieter (for about 5-10 shots). I shot the Advanced Arm .300 can on my Rem 700 and it's about .75% of a .22 rifle with no recoil. using regular ammo.

[harley19770]

I want one for my GLOCK 10MM

[spraynpray]

It's gonna be really loud.

[koho8000]

love the glock 19. I was just firing it today. =)

[arickard]

shot 100 rds of PMC yesterday out of my 19! :D

[sbejarano]

Depending of the purpose of the action:

If you are going into a very short distance action and you need supressor to conseal your presence then subsonics are just the tool required, if you need to supress your supersonic boom on a high power bullet at 30 meters you are better of with a high speed bullet low grain, finally if you want to stop a 300 pound guy attacking you under the influence you better get a higher grain bullet some HydraShock will do the job.

Silencer is to minimize detection.

[MOBROOKS]

this video is so amazing! I want a suppressor so bad! its like pulling teeth trying to find a thread barrell along with the suppressor.

[Moszczienski]

whats the name of that song at the beggining?

[stllopez314]

The name of the entry song is "Name Of The Game" by The Crystal Method. :)

[HugeWeights]

a suppressor is so pointless unless you actually utilize subsonic ammunition, but man when you get a suppressor that can properly dissipate energy and you combine it with subsonic ammunition, its a thing of beauty

[ethtreyu]

agreed

[pnuemagger]

I'll have to disagree. What about rifles whose projectiles rely on thier energy & speed for effectiveness? 5.56/7.62/.338/etc

A good suppressor:

Acts like a muzzle brake trapping gas and reducing recoil significantly & killing flash.

Aids hearing protection by knocking another 30dB off the shot in addition to your 20-30dB earmuffs.

Creates more cosistent gas flow and smoother bullet transition thus tightening your accuracy.

Subsonics may be a plus, but the big picture is larger. ;)

[jebustheone]

I love the transition :)

[1Agent19]

aren't suppressors illegal unless your in law enforcement?

[natemanrulz]

not on all weapons. Silencers on pistols for home defense. less noise means easier on the ears if fired in such a closed area

[1Agent19]

Sweet! thanks for the info!

[natemanrulz]

anytime man

[762sd]

They are very legal in states that allow them.

[HugeWeights]

well here in north carolina, a civilian like myself can get them, you just have to either have a class 3 liscense, which i believe you also have to have a FFL to get, i think, or the easy way is to get your local sheriff to sign off on you getting the suppressor or pre 86 machine gun

[GunsAnd90sRock]

Very nice. That's the same company that makes the supressor I use with one of my 1911s. Great video!
