Suppressed 45 acp

[TimS]

I have an FNX 45 that surprises me with its accuracy. I’m using a Silencerco 46 hybrid but am disappointed with the suppression. Is there a suppressor that is quiet? It is a subsonic cartridge. I have 6 suppressed firearms but I’m disappointed with the sound. Anyone experience o good suppressed 45 that can share their experience?

Thanks

TimS,
I run a SilencerCo Osprey 2.0 45 on my H&K MARK 23. This was my first suppressor, I like it and have different pistons so I can run it on my 9mm carbine. No issues when shooting without ear protection with the 45ACP. Also, about 5cc of water also reduces the sound level as well to include that first round crack. No issues with the sound, the only thing I have compared it to is my Grandsons Otter Creek 9mm suppressor. Have a SilencerCo 46M on the way which I could run with a piston as well.

Just my .02

I have an AA Ti-Rant 45 for my HK45CT that is also disappointing with the size and the sound level. Not sure why since the ammo is subsonic. I can shoot it without hearing protection but it may be right at the edge. I'm glad that I didn't spend the $$$ on the suppressor height sites.

kelbro,
Nice setup. One of the main reasons I went with the Osprey was that I could still use the factory sights without having to get suppressor height sights.

Thanks. I've never tried mine 'wet'. Never really even heard of adding water. I might give that a try.

Here is the H&K with the Osprey 2.0 (45).
The water or wire pulling gel was recommended by the manufacturer.

"Hollywood quiet" only happens on movie sets. And "quiet" is very subjective. "First round pop" - where the first round fired is pretty noisy - is a real thing. "Quiet" is the factor of how far below 1050 feet per second Your round is traveling and the length and quality of your can.

Are you sure the ammo is subsonic? Have you measured the velocity?

If you load your own ammo, try a powder that is faster burning so the pressure drops near the muzzle.

Not sure any powder burns that quick... in 5" of bbl..

You slow a bullet down by using less powder..

You talked about the ammo being subsonic.

You don't get subsonic ammo by the powder burning faster , you get subsonic ammo by using less powder. Look at ANY reloading manual... bulletspeed in pistols is directly related to how much powder is used.

"Pressure curve" is irrelevant.

Again, I am not talking about bullet speed, more about the pressure curve and muzzle pressure. More muzzle pressure makes more noise.

For example, 45ACP 230 FMJ-

8.0 grains Accurate #9
MV 633 FPS
Muzzle pressure 2400 psi

3.4 grains Titegroup
MV 638 FPS
Muzzle pressure 1719 psi

SUBSONIC IS ***ONLY*** ABOUT BULLET SPEED.

Muzzle pressure HAS NO RELATION to a bullet being subsonic.... which is ALL ABOUT BULLET SPEED.



YOUR OWN POST PROVES MY POINT... 5 FEET PER SECOND DIFFERENCE AT A LOWER SPEED HAS SIGNIFICANTLY MORE MUZZLE PRESSURE.

YOU used the word "subsonic" and it's the wrong word for what you're trying to talk about. Sub sonic is about the speed of the bullet after it leaves the barrel.... When it exceeds the speed of sound in some twenty feet past the end of the barrel , it causes the sonic crack.

Sub sonic is the wrong word. Stop using it.

With my rimfire cans, all that you can hear is a popcorn fart on the first round and then the slide slamming shut on subsequent shots.

The 7.62 SDN can on my 300BK is almost 'Hollywood quiet' after the first shot.

This 45 can is not anywhere near as quiet as those and yes the ammo chronos subsonic.

Rimfire is its own animal.

Have you ever shot your 45And your 300BLK can side by side? I'm betting , if you measured them on a decibel meter , they would be pretty much the same volume. My 300 black and my Glock 9mm are about the same volume. It's one of the reasons I only suppressed one or two of my center fire pistols.

"Quiet" is very subjective. We expect a rifle to be loud. And so the rifle can seems really quiet. We expect every pistol can to shoot like 22 rimfire and so when it doesn't , we think it's pretty loud. It's kind of like the people who think nine millimeter is really snappy in a PCC. Highly subjective.

Everybody has their own personal experience and\nSubjective evaluation of how loud "quiet" is. So I can't really make any universal statements about that. I'm just trying to suggest to the OP not to be disappointed. There may well be nothing wrong at all with his setup

I need to get my wife to shoot both while I'm standing off away from them a little. My 'gauging' has been from not having hearing protection on an is subjective.

I also suspect some pistols are just not made to suppress. Their action cycles in such a way as to let more gas escape than other pistols do.

And as another poster was trying to say .... the burn rate of the powder may be so slow as to have a lot of combustion happen inside the can chamber , rather than in the barrel, and therefore to the shooter will sound "loud." Another ammo with a different powder may sound noticeably different. Maybe.

One thought about that... i know I've done so much shooting that I don't really trust my own ears anymore. I'm sure I have at least some level of hearing damage.

You may want to shoot them yourself and have your wife stand a little ways off and have her tell you what she's hearing.

Maybe.

I used paragraphs to separate the subjects of subsonic velocity and muzzle pressure.

They are two different things.
