Maxim 9 dB Numbers

Armory » Silencers

Posted: 11/10/2018 4:16:02 PM EDT

I haven’t seen any numbers beyond what Capital Armory and MAC have posted on YouTube. Seems like with both of these it averaged around 126-128dB in long configuration at the muzzle with 147g.

My question is that on SilencerCo’s own website they have it listed at 136dB. Seems like the manufacturer is really conservative?? Any other third party tests besides those I mentioned?

I don’t know, but I have a Maxim 9 and I’m interested. I’ve read Mac’s meter doesn’t have a milspec rise time and shouldn’t be trusted, but I don’t know. Mac’s at ear results were better in the short configuration and that has me wondering.

Can you screw a second can into it? Can on can?

That is not unusual for the at ear number to be better with a shorter baffle stack given the decreased back pressure. Or are you saying that gives validity to his meter?

No it doesn't sound conservative to me.

Ive shot one. Its still pretty damn loud. Id take SiCo's word

I’m saying neither. I would like confirm that the Maxim is quieter to the shooter in the short confirmation as that’s how I prefer it, but that confirmation doesn’t (maybe can’t) come from the Mac’s ‘random number generator’ meter, as others call it.

Both MAC and Capital Armory metered very close to the 139dB SiCo rating in short configuration which makes me think they are accurate. Also typically seem to be close with other cans vs manufacturers numbers..just still seems odd to differ 10dB on long configuration.

Agreed. The Maxim is a really cool weapon, brings suppressed CCW into the realm of feasible, but it's not particularly quiet. While I haven't seen one metered in person, I have shot them, and I'd be surprised if it's as low as 136.

Any of you in No CO area with a bunch of pistol cans that is interested in sound testing let me know. I have to say my pistol suppressor collection is lacking. I guess I should change that.
So all you manufactures on here please send me your best 9 and 45 cans. I'll do a big pistol can test. Please message me on here or drop me an email for my FFL/SOT

Two people getting same results does not mean it is accurate

How could they be accurate if there’s a 10db spread in long configuration? That makes no sense.

That’s my point of the thread. They seem to agree on short configuration but huge difference in long. They also meter close with other cans. It’s the biggest spread I’ve seen and many reviews state it comparable to the Omega 9k which is in that 126-128dB range...

Even SiCo has the 9k listed at 131.5, and I'm betting it meters at least 136 with subs if Ray tests it on the Pulse. The Pulse is more than a little revealing on the innaccuracies of many meters and advertised figures.

I'm guessing it's a typo and should be 126.3. It doesn't make any sense a 115 is 137.1 and a 147 is 136.3.

136.3 doesn't make sense.

That's a hell of a typo to propagate through all of their Maxim 9 literature, though. You should talk to your SiCo rep and see what's up, including remetering it if necessary.

Any idea where you will post results when you're done testing? I know I'll want to read them.

Sometime typos happen and nobody catches it - I work in marketing.

No, it has a short internal barrel then the baffling. No exterior threading.

Call the shop and ask for me. They will transfer you to my cell 303 287 2052 we can set something up.

It doesn't take long to get results sorted. Usually a day or so depending what else we have going on.
