Need help choosing a new M&P and suppressor set up

[tlawler]

I'm getting ready to make my first foray into the world of suppressors and would like some advice. I'll be purchasing a suppressor ready M&P to use it on along with the suppressor. I only know the basics such as: it's best to stay subsonic for best suppression and something in the .40 or .45 caliber range is probably best.

What would be the best way to go? What brand is better than the next, etc? I would like multiple caliber capability, but not necessary. At some point I'll probably add a .22 suppressor and firearm to my collection also, but I thought I'd go with the larger caliber first.

I do have an M&P 10mm 4.6" that I thought I might get a .40 cal barrel for, but I can't seem to find a compatible barrel. Does S&W or aftermarket even make interchangeable threaded 10mm and .40 cal barrels for the M&P?

Thanks guys, this is a whole new world to me and I'm looking forward to it!

Call Zach Ely at SilencerCentral 888-781-8778. I believe his cell is 605-349-4337. He is THAT guy if you are even thinking about buying a can.

I would highly recommend a .22 can for your first suppressor. I have a Dead Air Mask HD, and it has been fantastic. Very quiet and easy to maintain. I have several other cans, but shooting .22 suppressed is probably the most fun. My .22 can gets shot more than my other cans combined.

My 9mm Rugged Obsidian is probably the one that gets shot the least. Any centerfire handgun can that is going to be quiet will be large and heavy enough to be ungainly out there on the end of your gun. You can't really work from a holster with a suppressor mounted. Large bore handgun cans may or may not work on 9mm depending on the mounting architecture and the ability to change thread pitch on the piston. Some handgun cans can also be used for .300 BLK if you have one.

If you shoot rifles, I would recommend a .30 rifle suppressor. Cartridges like .308 and 6.5CM are very pleasant to shoot suppressed. Be prepared to tinker if you're going to mount them on a gas gun.

5.56 in an AR is something you really can't make quiet. You can get them below hearing damage levels, but they're still going to be loud. You can use a .30 cal can on a 5.56 without a lot of efficiency loss, so a .30 cal can is a better investment.

So, TLDR: Buy a .22 can first, and a .30 cal rifle can next (if you shoot rifles). Then just buy the rest anyway... because you will.

I agree with the above advice regarding a rimfire can. I have both rimfire and centerfire cans, and my rimfire can gets shot easily 5x my centerfire ones. They're cheap (relatively), fun to shoot, quiet, etc. A real fun setup.

Among my .22LR hosts, my M&P22 Compacts are my favorite. They come with a threaded barrel, eat anything, and the 3.56" barrel means even cheap bulk-pak ammo stays subsonic. No need to pop for the pricier subsonic .22LR. If your Compact didn't come "suppressor ready," the most you have to do is spring for an adapter, and those are like $20.

The good news, I guess, is the M&P9 suppresses well. I have a couple of 9mm cans, and they all work well with the M&P (as opposed, to say, my G19, which unlocks early and spits **** in my face). In order to get the most out of a centerfire pistol can, you need subsonic ammo ($$), a threaded barrel (~$100-$150), and the right piston for your booster (I have a little box of pistons, 1/2-28 for 9mm pistol, 13.5x1mm LH for the Sig, 1/2-36 for the carbines, etc.) It all adds up. And I enjoy shooting other pistols suppressed, but nothing is just as easy and fun as .22LR. It's rare, indeed, that I go to the range without a .22LR and suppressor in the range bag, even if I don't plan on shooting it. Just too much fun.

I don't disagree with the advice regarding a .30 rifle can as a first choice, even though I have a couple of dedicated 5.56 cans more or less permanently parked on my AR15 SBRs. A .30 rifle can is pretty versatile, and the only down side is you find yourself having to commit to a QD system, and then every rifle you plan to suppress ends up with that muzzle device. Much brain matter has been destroyed worrying over which QD system to commit to.

Be advised: no one owns one suppressor. Accept that now.
