9mm?

40?

45?

Which and why? It would be cheapest for me to buy a threaded barrel for my M&P CORE but I have a friend that claims the .40 sucks suppressed even when using 180's that are subsonic.

Otherwise I am planning on an entirely new pistol. Same friend claims the 9's with 147's are nirvana.

Have shot 147gr 9mm thru a 45 TiRant and it was noticeably quieter that 45, so I'm sure a dedicated 9 can would be better. Both calibers were through Glocks. Shooting the cans wet made a huge difference. Never suppressed 40. The biggest giggles are from a 44 Ruger rifle with 44 special speed loads.

9mm 147 or .45 230. Done. Hell, a .45 can will work (though not perfectly) with .40s and 9s as well (and probably .32s, but that's just a guess).

It's a 45 can.

I'm asking what people prefer in chamberings when shooting suppressed.



Dave

Ah.

I don't own one (yet), but have and do shoot a bunch owned by friends. The .40 just seems louder, no matter what. .45s can be silly quiet. 9s, too, but the .45 ammo range for subsonic is broader. Either seems to work, and when a 9 is quiet, it's damned quiet.

flave, no 1st hand experience yet on centerfires. Have an Omega and Hybrid that will be in 41P purgatory for a while. So, it'll probably be eoy before the dust settles.

But, for what it's worth, heard the same you have on 9mm.. 147's are the shizzle.

The smaller the bore the easier it is to suppress the noise. That's why 9mm has been the preferred handgun caliber for quiet work...that's what they told me at ninja school.

Yeah. I think I'll get another M&P CORE.




Dave

My only experience suppressed centerfire was a 9mm Beretta.

Nothing really to compare it to, but I didn't have any problems with it, and I shot it a lot.

147 gr.

The info regarding the .40 surprises me.

I hate to buy another handgun but a man has to do, what a man has to do.

PS - A .25 saved my life Sunday. Rattler came up behind me when I was shooting prone. Just got my hand on my EDC and my spotter lit him up. 9 rounds of awesome.

I'm reloading for my quarter bore now, to maximize its capabilities...

Flave - they are all fun but 9mm is definitely quietest. 40 kinda sucks in comparison; higher muzzle pressure and larger bore.

If you already have the suppressor and just need a threaded barrel swap for the 40 though, might as well try it. Suppress all of them; some are better than others but they're all better with mufflers.

Side note - if you load your own, subsonic lighter bullets run quieter than the heavy stuff; less powder and pressure required. 125gr 9mm subs, for example. Remember muzzle pressure = sound, still applies through a suppressor.

Do you think it's worth it to try loading a schit ton of subsonic 200gr stuff and buying a threaded .40 barrel?

I won't be switching the can around. Once it's on a gun it will stay put. I'm basically just trying to decide if I should go 9mm or not.

My goal is Hollywood quiet or as close as I can get to Hollywood quiet.

imi, ppu, and american eagle are making 124 and 158 grain subsonic 9mm ammo

and the 147 9mm is stupid quiet

rock

Yeah. I was told the AE 147 stuff is da' bomb.

I forgot what I ordered but was just told it's the AAC T-Rant-45.

I can get this for a pretty decent price. Seems like the logical route if .40's suck.

If you're keeping the can on one gun, and want it to be as quiet as possible, go 9mm. I wouldn't waste time with .40 in your case, unless you're going to load your own, something like 140gr cast subsonics maybe.

Have you heard or fired suppressed centerfire pistols before? If not, you might be a bit disappointed; actual "hollywood quiet" setups are pretty rare, and require a perfect combination of gun, suppressor, and ammo. Suppressed 9mm pistols can be pretty quiet though.

I have shot a number of suppressed weapons but can't recall a .40. And I think the 9's I shot were not subsonic so they're not a real good reference.

I have a .308 can and a 22LR can so I'm somewhat familiar with them.

Seems like 9mm is the consensus. Thanks for your help.



Dave

Clark,

You could just get a .40 to 9mm conversion barrel that's threaded for your .40 M&P; they work very well, even suppressed. There's several companies that make them.

I thought about that.

But it seems kinda Jewy.


Dave

And do they require a different rod and spring?
