Don't remember where I got them, they were not available for a while but now are.
 
Attention. Sgt Mike and Bohunr. You both mentioned the 9mm PCC and I wanted to ask if one of even both have a can on one of these? I ask only because with the 9mm you used to have to have a suppressor with a neilson device. This was for a pistol. What about the PCC? I have not checked into one.
9mm makes a lot of sense and I can imagine it would be fun too.

Yes I have a Yankee Hill Machine Wraith XL in 45 on my 9mm SBR (now discontinued for several years now , the R9 they offer would work in it place though).
It (Wraith XL) is a dedicated all aluminum can for SMG, no provisions for neilson device which is not needed for Blowback operations.
It's the same can I had when it was in a Pistol format before completing the paperwork for SBR registration. Only added the normal Ar-15 Carbine buttstock, everything else is the same as before, once I got the approval Paperwork. The Yankee Hill AR that I had in 9mm the son wound up with it. That one needed no tuning ran straight out of the box, screw a can on and go.

That being said If I had a can that usually offers (or had) the neilson device as in a pistol can, they can usually take a direct thread adapter. Because of the operation being blowback the can doesn't need to send a recoil pulse or slap backwards to function the SBR / PCC with direct blowback. Same holds true for say the Walther PP pistol the neilson isn't need to function, as the PP and PPK is direct blowback.

I have looked at the CMMG RDB (Radial Delayed Blowback) in 9mm , looks to be a bit easier to tune verses playing with the buffer and bolt weights in the pure blowback colt configuration. (here again the neilson device is not needed, from what I've been told.)
The bolt that CMMG RDB has closely resembles the 5.56/223 bolt in the lugs, but that is where the similarities end, function is different. Where the original colt design isn't using locking lugs basically a block in some sense, no rotating bolt much like a pistol slide . One way to describe it it's not really a accurate description, but gets the point across.

How quiet is it? with true heavy subsonics (158grs) all you get is pretty much the bolt slapping noise. Supposedly the RDB CMMG is quieter and smoother than older Colt Design that I'm running. The HK MP5SD is the absolute smoothest recoil pulse and the quietest I have ran, Sadly I had to give it back to my Uncle Sam after every time I shot it.



(looks' like Northwest Firearms still has two in stock, although at their listed price I think I would snag a R9 , I definitely didn't pay that much for mine. They usually include a flash hider for attachment which is what you might be thinking of vs a neilson device)

I run a 45 cal rugged suppressor on mine. You can use either a DT adapter to replace the booster/piston or they make a solid sleeve that slips over the booter/piston, replacing the spring thus making it (the piston) solid and inoperable.
 
go with a fast twist ar chambered in 223/556 and run 40-55gr VMAX for your self defnense loads.

you'll have 30 little hand grenades that probably wont even come out the bad guys back and all but detonate once they get thru the ribs.

the TAP Urban load runs a 55gr or 60gr vmax. for that very reason - effective on target without over penetration.


and the light boys are drywall friendly


i keep a mag of 55gr vmax with my home gun... i dont have to worry about punching thru into the neighbor's house

especially with subs barrier penetration is going to be an issue.
big, slow & heavy = difficult to stop.

That was one for me which, about every point in this thread put me in the 9mm camp. Not everyone will have that issue especially if the kids are grown, out of the house. And it's just you and the wife.
The BO is worthy of consideration, in my case it just wasn't the correct hammer. It very well maybe for the OP. I'm not touting that the 9mm PCC is "the" answer I'm just relaying why I went that route.
 
Barrier penetration - I shoot primarily the 110 vmax from the BO rifle @ 2400 fps. It would be about 2k fps from the 10" pistol (never chrony'd). Gboy and I could not find entry or exit on the yote I got @ 150 yds. broadside hit (~1/3 energy loss at that range). The GD BO bullet is supposed to expand down to 1400 fps, never recovered any I've shot at targets. For HD, barrier is not on my mind. With a good RD, the BO pistol would be a great HD or truck 'gun'. Decent longer range and easy handling rig. Yea, I got a running hog @ 20 yds with 40sw pistol but took 3 shots to 'get it right'.

at BO speeds, the 110 vmax acts more like a standard cup and core hunting bullet. nice mushroom, pretty high weight retention. one of the best deer bullets you can use for the cartridge without getting into the fancy engineered stuff anyway.

out of a shorter barrel (pistol/sbr) at across the room distances, its proably gonna go thru 2-3 interior walls before it stops.

gonna be damned mean to the bad guy on the receiving end though thats for dang sure!

I was disappointed in the terminal performance of the 55gr TAP in my shooting. At about 50 yards, I hit the guy just above his nipple and the second round went downward into his body cavity after entering the clavicle area (he was bent over slightly from the impact of the first round). His lungs were quite shredded.

He died for sure and there was no amount of aid that would have saved him, but he regained consciousness before expiring... he could have resisted temporarily if given the opportunity. I highly recommended we increase the weight of our duty round but that never happened.

Personally, I love the AR platform and use it for hunting, recreation, and HD... but I'd like a heavier round in the 65-77 grain weight range for HD. The 55gr TAP will kill... but for immediate incapacitation, you will need a CNS hit to compensate for the small dia. and light weight. Multiple hits are a must if using the .223 and light weight projectiles.

The .300 BO with something like a 125gr Ballistic Tip or 125gr SST at super-sonic speeds would be pretty darn effective I would think. I bet the 190gr Sub-X at sub speeds would be quite nasty. The Barned 110gr Tac-TX would be an excellent choice as well.
 
I don't have children or a house full of people so I'm not really worried about overpenetration. Right now for HD I grab two weapons. A XDm 9mm loaded with 147gr Federal HST's and 147gr Winchester Ranger XT's and a 12ga (HD model) loaded with 00 buck. I feel very confident that I could handle 99.9% of "home invasions", however.... as I stated, things are getting worse by the day around here. I just want something that I am confident with those 00.01% that may include 3-4 crack heads kicking in my door because that kind of thing is happening more often these days. I also live 15 COUNTRY minutes from the nearest police station and my nearest neighbor is 1/2 mile away.

I know that a pig isn't a human, but I've shot enough pigs in my time that I don't really see me trying 55gr vmax's for any kind of personal protection. I've just seen way too many pigs keep going like a bee stung them. I don't have to worry about that nearly as much whenever I use a good solid bullet like a 75gr GoldDot or 62gr Federal Fusion.

A friend of mine's father is a retired DC police officer. He has told me about all kinds of shootings that he's either been part of or witnessed. He told me that you would be amazed at what a person hopped up on dope could do after being shot. One of his stories that always comes to mind is he said he responded to a robbery at a convenience store where the man behind the register shot the robber center mass with a load of 12ga 00 buck and he still had enough adrenaline/drugs in his system to turn around and run several yards into the parking lot before he collapsed.

My friends father was actually shot himself during a traffic stop. He said the only thing that saved his life was that the man who shot him reached for the .38 instead of the .357 he had in the seat beside him.

i dont have a can on mine yet, but i did get to play with the airport police suppressed H&K 9mm years ago. i was impressed with how quiet they were.
