Omega 9K 1st can. Meh.

Unless it's drastically quieter on my AP5 than it was on my AP5K I'll say, "Meh". (Fiocchi 147 gr and 158 gr PPU)

I was hoping it would be considerably quieter on the Vz-61 (Trilug adapter) than it was on the K, but not really. I mean it is quieter on the .32 but in the same bracket.

The bracket is it's hearing safe for a mag or two.

The Omega 9k made my guns sound like a sub-sonic .22 does without a can. Still loud enough you should wear ear pro. And loud enough that a listener 100 yds away will know you're shooting a gun. (I think)

So what does it get me? Well, I can shoot with just muffs, and it would be fantastic for HD because it's quicker than throwing on electronic ears.

I couldn't use the can on the AP5 because the trilug has too much play. I ordered a direct thread adaptor for the can.

Should I get a full-size can or will I be somewhat disappointed with that, too?

Hollywood is a facade.

I’ve always heard to start with a full size can because almost everyone that starts with a shorty is disappointed in the sound reduction. You’re already into the NFA world now, might as well have a full size too.

I think the Omega 9K is the best ban SiCO makes. The suppression it provides for the length makes it a super practical can.

I use mine on pistols most of the time but appreciate the flexibility to put in a PCC or 300blk SBR to take the edge off.

Probably a good idea.

Hopefully my adapter comes in so I can try it on the AP5.

I'm not expecting it to be dramatically quieter. But a little.

Considering next a full-size can for .32 / 9mm or a .223 or .30 cal. can for a .223 16 in. rifle.

I've been waiting for Allegheny Arms to get Beretta .32 barrels but they won't be any quieter than the Vz61. That makes me think either I won't bother or I need a bigger can.

I knew the K-can wouldn't be as quiet as a full-size can.
I was hoping for very loud hand claps, port noise, and action noise. But I got unsuppressed .22 / fire cracker-level noise.

You're not gonna get "very loud hand claps" with a full-sized can, either. The loudest recorded hand clap was 117.4 dB, and the record before that was 113 dB; a suppressed .22 LR using a full-sized can is as loud as 113 dB.

The human ear is terrible at judging volume without side-by-side comparisons, and even then, it's not very good.

Beyond that, while someone might be able to hear a suppressed 9mm shot at 100 yards away, would they know what it is? The change in acoustic signature is one of the key advantages of using a can, beyond simple suppression, along with visual signature reduction.

Thanks for the insight.

Ambient noise drastically influences the way that we perceive, or don’t perceive, noise.

The way that you perceive .22lr subsonic unsuppressed to be similar to 9mm subs, suppressed, is about on par. Even with a very good silencer on a semiautomatic host, action noise is very loud.

Drop the bolt empty on your host a few times late at night in your quiet house while your wife is sleeping with an open door in the next room, and you’ll see what I mean. HK slap. Better yet, don’t actually do that, just think about it, because I don’t want your wife to murder you for waking her up several times.

Point is, you may need to manage your expectations. Your Omega 9k is widely said to be a very good can, especially for its length. You should definitely get a longer can, just because, and it will be fun to compare them.

I compared the Omega 9k vs DA Wolfman and thought the Wolfman would be a much better choice.

The DA is very versatile and can be run in short and long config. Friend got both. I tried them on my Banshee 8”. The wolfman in short config is quieter than the 9K with subs and supers.

I couldn’t tell the difference between the short and long configs with subs by the way.

I've never found any of my suppressors on any of my hosts to be quiet per se except 22. subsonic. The noise & blast reduction makes the experience significantly more pleasant and enjoyable. Indoors on the rare occasion I want to get inside with poor weather outside, suppressors are a godsend, especially on any long gun.

All this.

Running the can wet will help the 1st shot or 2 as well. Rem oil or wire pulling gel (one that evaporates clean) are good.

Wet, eh? I forgot about that.

I think I read water can work, but of course can lead to corrosion an doesn't stay in the can as long as oil. Right?

How about a spritz of olive / vegetable oil? Seriously.

Yessir, even a few drops of whatever brand CLP, a bead of grease, a smear of Vaseline, or 3cc of water can improve performance noticeably.

I’ll check tomorrow. I bet it’ll work. As to water, I’ve submerged these things and drained them, and also swished them in rainwater, and its been fine. Lube the bolt afterward, because the steam does come back.

Some oils and hydrocarbons leave more filth than others.

Dont use veg oil. It will leave a residue and go rancid, and make a whole mess... it gets nasty.

Water is nice because it doesnt smoke (the steam dissipates much faster), and is quite effective.

Right, good point. Thanks.

I suppose with a short / "K" can one is getting roughly 80% (WAG) of the suppression a full-size can offers and that's why they are popular.

Less weight and length but not far away from the performance of a full length.

I've now got a .22lr, 5.56 and 7.62 cal. cans paid for and in process.

"When should I order the suppressors I want?'

Answer: "12 months ago."

Now you’ve got the idea. A proper pistol can is next.

I dunno yet. I found a can meant for .32 acp I could shoot .32 and also .25 acp through if I get Beretta barrel threaded.

And while I'm selling off some .45 acp pistols I've got a Beretta96A1 .40 I'm going to put an RDS on. Perhaps someone makes a threaded barrel for that?

Really though, I think I'm going to get the most enjoyment from cans on rifle calibers and the .22-.32's.

Edited to add:
.40 through a .45 can would be louder than 9mm through a 9mm can. .25 acp through a .32 can louder than .22 through a .22 can. So I think I can drop those ideas.

If I do the .25, I need a .22 can bored and marked to be a .25 can. .25 uses fast powders. Could suppress better than .22lr. I dunno. Want to try.

Ecco Cheetah?

I wouldn’t worry too much about the .25 being underbore for a .32 can, given that its prolly a teensie short blowback gun.

Yup. Would look good in Dark Bronze.

I probably should have tried harder regarding getting a .25 threaded before getting the 21A .22lr. But with the current $150 rebate going I went ahead and got one.

.25's are more reliable and with FMJ bullets and faster powders wouldn't dirty up a can like .22lr does.

The point is a can that is usable and not cartoonishly large but yet still hearing safe. Love my Omega 9s.

Okay I've changed my mind and have come to appreciate the Omega 9k.

I appreciate the shorter length & lighter weight.

What also helped push me into the "fan" corner is I found it's hearing safe on my Beretta M21A .25! Yea, a little big for the M21A, but it works great!

Works well on my Beretta Cheetah .32's and VZ61, too, when using milder loadings.

~ decade ago, I sat in the basement of SiCo for a week, working on this.. what became the 9K, as a professional end user. Made of off the shelf parts bin components, used in a novel manner. Larger rifle baffles welded together sans tube. I wanted more internal volume and was using optics on glocks, so a fatter tube was fine and did not obscure view. Added and subtracted baffles until I got what I wanted... factoring in -shoot ability, -concealability, -noise

Longer cans have crap handling and recoil characteristics.
It was just short enough to conceal under a jacket.
Decent suppression. It is robust for a pistol can and you can safely run it very wet... noticeably quieter.

This design sat in the basement for months and became a favorite of the employees shooting down in the basement range. One day SiCO called and asked if they could produce it for commercial sales. I told them no problem.

I have not tried the new SiCO compact Tii pistol can, but looks promising.

Well, thanks for it! (I'm the OP) If I see them on sale I'll probably buy another! That way I can semi-permanently secure the adapter. One for direct, one for tri-lug.

It won me over.
