MP22 Compact thread adapters

[dullh]

Stalking Rhino makes me nervous. Their website is bare and and their phone number goes unanswered.

I ordered my 22c thread adapter from Twin Tech Tactical in Texas...it's on the way now. I bought the 22c for the sole purpose of suppressing it...thanks to a member of this forum I found TTT...

And by the way BigWaylon, just submitted my 4th F4 for the original Spectre II I was going to buy to begin with...dealer called last Friday and said "it just came in do you still want it?"

Dumb question...

 

[WilliamG]

Got the wrench and barrel bushing. Wow, EWK. Just wow. This is a super heavy-duty (and I mean heavy!) wrench!

And the bushing works a treat. Fit nicely, no adjustment needed, and it re-centers the barrel very, very well.

I really think the .22 Compact is design flawed in this regard. I know it was "designed" to rub like this (for better or worse), but you really need a bushing to fix it, or a tweak in the design of the pistol.

Anyway, a couple of pictures showing the bushing, and the centered barrel.

I really have absolutely nothing but positive things to say about EWK. They advertise only what they have available, they ship before I've even had a chance to wonder if it's shipped, it shows up very quickly and just works. I wish all purchasing experiences were this good.

Good decision. I'm waiting on my second one to be approved any day now. Picked up my first Warlock II yesterday. At 3oz, it almost seems as if somebody forgot to put the baffles in it. The Spectre II feels like a tank compared to the Warlock.

Speaking of tank...random suppressor pic coming. Dealer had a Salvo 12 (it's a 12ga shotgun suppressor to save anybody the time of looking it up if you weren't familiar with it) on display. Hasn't seen one in person. Took a pic of it next to my YHM LT (.30 cal can):

I'm the FIRST person that complain about the barrel rubbing on the slide online, Some members online thinks I'm over react about O.C.D.

I have seven .22 pistol, I like a kids to take things apart and learning functions on all my guns. I like Smith warranty, but it take few weeks to get it back.

Finally, EWK have a good idea to make some things like that improved the Compact. I had talk to Smith customer service about the EWK bushing.

I got mine too, It's look nice and heavy duty on the wrench. I also got 2 bushing, I have to wait for Smith send my Compact home.

What's next? After markets SS barrel, Apex trigger, Sights

Lighten up, really. You didn't discover a new planet or something. MANY of us noticed it was rubbing immediately. Heck, I noticed in the store before even buying the thing that it was rubbing. Why do you think I told you not to bother sending it in - because it's normal!

Now whether it's GOOD for the gun or not, S&W decided this was how the Compact was going to work. Like you, I'm being proactive about it with the bushing from EWK, but let's not lose sight of the severity of the issue - which right now is unkown, and nobody is complaining about their .22 Compact falling apart. Time will tell.

FYI, The wrench will work on the full size .22 and P22 as well.

Oh interesting! Well spotted.

 

[ewk_stuff]

Thanks so much for the report on the wrench and bushing!

Isn't the wrench kinda of loose on the full size? The flats on the full size should be around 10MM? (.394") The wrench is made to fit the .416" flats on the compact's factory nut.

I use the Threaded Adapters from SilencerCo for the M&P 22 full size and P22, The flats is 10.10mm, and your wrench is 10.60mm, It will work.

Unless a S&W engineer/designer/tech chimes in, nobody can say for sure whether the barrel/slide rubbing is even an issue.

Most all semi auto pistol slides rub against the barrel during movement. Some more than others, and to varying degrees. It's never perfect clearance where it's like a free floating barrel on rifles.

With the m&p22 compact I can clearly see from looking at the barrel/adapter underside that the slide is in constant contact when cycling. But the action is silky smooth and doesn't affect accuracy or anything. In terms of wear and tear, the slide is aluminum and the barrel is steel... so no concerns over barrel damage there.

But like i said, there's really no definitive explanation about this unless someone from S&W gives us a technical answer. Nothing is exactly "broken" here but people are quickly jumping the gun trying to "fix" things.

I agree. That said, I see no harm in reducing the amount of rubbing taking place.

Sure, if you are happy with the factory setup, then go for it. I'd say any answer from S&W will be there is nothing wrong with it. (Which others have found out already sending Compacts back to them complaining about the rubbing issue) S&W seems very reluctant to release inside track info, so I doubt we can get the exact inside track on this...shoot, when I was buying tooling out of the Houlton plant a few years back, couldn't get much more than the tooling and I think that's a pretty good inside track...I think the guy was the manager if I remember right?

I too would love to know S&W's thinking behind this design...everything that is running through my mind isn't making sense! One comparison I have heard is that to of a 1911...but that is steel on steel, and the barrels are straight and don't have a step in them like the compacts do.

Also a 1911 is a completely different design than the compact-the 1911 has a floating barrel that locks up in the slide, so we need there to be angular displacement between the parts for it to work.

The compact has a fixed barrel with a straight blow back action, so why would we want angular displacement of the slide? The more square the bolt face is to the breech, the better...no aluminum to metal contact...no "step" the slide is having to ride up...

Just got my Compact back from Smith last night from UPS. Do to my sight blade fly off over 3 weeks ago at the ranch.

Put the new centering bushing on the Compact last night. Head out to the ranch to readjust the sight. End up stripping the windage screw. Because they put glue on the Adjustment windage screw. Call up Smith customer service and explain the problem that the person put LOCTITE glue cause stripping the screw and allen key. They are send me a fedex label for the 3rd times in 2 month.

After I install the bushing, I had few won't eject all the way out cause stovepipe. It this normal for the bushing?

 

[Ghostmaker]

Been lurking here for a few days and I thought I would add my insight. Here's my opinion, for what it's worth.

1) Bushing rubbing on bottom of slide -- This is how the gun is designed. The barrel isn't rubbing on the bottom of the slide, the bottom of the slide is rubbing on the barrel. Unlike a GLOCK, there are no rails on the front of the slide. Literally, the belled barrel bushing (or adapter if you replace it) is what acts as the front slide rail. It is this way on the Walther PP series as well as hundreds of other designs. Rule of thumb is that if your gun disassembles by pulling the slide back and lifting up, then the bottom of your slide probably rubs against the barrel. It isn't the barrel tilting down when you take the slide off, it's the slide tilting up.

2) The fouling on the inside of the hex flats inside the EWK adapter -- virtually a non-issue. When you insert the allen key, it pushes the fouling out of the way. Just make sure you clean the threads and barrel after you take it off. As far as it getting fouled enough to cause baffle strikes... WHAT? The inside of ANY adapter can foul, and there are several with less clearance than the EWK. Just the fact that you must remove the adapter to disassemble the gun means that it will get taken off (with the Allen wrench) and that will clear any fouling long before it gets thick). Again, no more an issue than with any other adapter.

3) The wrench -- I am taking a 10mm Bicycle wrench that is thin enough and filing about .5mm off one side. Done. Only plan on using it once to get the thing of then leaving it in the box if I ever decide to reattach (of course, why would I?).

I put the adapter on and took some comparison pics.

SiCo M&P22 on the top, SiCo GSG 1911-22 in the middle, Twin Tech M&P22C on the bottom:
<snip>

Can you share your thoughts with the Twin Tech adapter? I've been trying to find an adapter for my M&P22 Compact. So far I've tried the:
- SilencerCo adapter (indexes on the end of the barrel instead of the shoulder, and tightening it chews up the threads at the muzzle)
- EWK adapter (ragged threads on mine chewed up whatever it was screwed on or in, and wasn't made to SilencerCo's specs)

I'd buy the Stalking Rhino version if it was available, but I don't know when that will be. So it looks like the only other options are TROS and Twin Tech (which is $40 cheaper). So I was hoping you or someone else could share your experiences.

Namely:
- does it index off the front of the barrel, or the shoulder?
- are the threads clean, any burrs or anything?
- is the o-ring engagement a snug fit? It should be .440 +/- .002 diameter. I think I measured around .434 on my EWK. It doesn't sound like a huge difference, but the suppressor was a lot looser on the EWK than the SilencerCo adapter.

Wait - can you explain in more detail what happened with the EWK adapter? Did it chew up your suppressor threads?!

 

[hoc9sw]

Wow. Just tried the EWK adapter this week, and other than needing to clean it up a bit, and the protector vibrating off, it worked fine with the Sparrow.

I'm also interested in what was wrong.

 

[sdl74]

No, it didn't damage the threads, it put nicks in the o-ring in the SilencerCo thread protector. That's when I realized I needed to clean up the burrs on the external threads. But there were more burrs on the internal threads that stopped it from going further than maybe 3/2rds or so onto the barrel. That, plus the undersize o-ring engagement diameter brought me here looking for another adapter. I've been lurking on this site, and this thread is what lead me to the various M&P22 Compact adapters initially. Hopefully someone will provide some feedback on the Twin Tech adapter.

Just like yours, the threads needed to be cleaned up. Plus the o-ring engagement diameter was undersized which meant the fit isn't as snug as an adapter that's made according to SilencerCo's specs. If you cleaned up your threads and tried your adapter, it's probably fine. Although I'd be curious to know what your o-ring engagement diameter is (should be .440" +/- .002).

Did you not have the EWK protector that came with the adapter?

 

[sdl74]

I did, but since I also had a SilencerCo thread protector, I figured I'd use that since it's nicer and has the o-ring engagement.

I don't want to derail the thread. My experience with the EWK adapter wasn't ideal, but maybe I got a bad one or it's better suited for people with more patience than me or whatever. Ok, I moved on, and if anyone has an EWK adapter and it's working for you, then it's probably fine.

Back to my previous question - if anyone is using a Twin Tech adapter, what are your thoughts after using it?

- does it index off the front of the barrel, or the shoulder?
- are the threads clean, any burrs or anything?
- is the o-ring engagement a snug fit? It should be .440 +/- .002 diameter

Or maybe there's another adapter out there (with the SilencerCo o-ring engagement) that hasn't been mentioned?

Not really a derailing. Very interesting to hear people's experiences.

Anyway, it sounds like at least some of the issue is you bought the wrong EWK thread adapter, since they sell two - one without O-ring engagement and one with.

Anyway, to get back on track (for you), I don't know the answer to your Twin Tech adapter question, but maybe someone else does. Hopefully they will respond here.

 

[hoc9sw]

My EWK adapter has the unthreaded o-ring area. There were two types presented when I made my selection.I don't have tools to measure to that detail. Being arthritic and completely uncoordinated, any tool is wasted on me beyond being an expensive aid to damaging something.

 

[sdl74]

I wish that were true and then I'd just buy the right adapter. But I did buy the one with o-ring engagement. The burrs at the end of the threads still made contact with the o-ring.

As annoying as the problems with the EWK adapter were, even more frustrating is that the SilencerCo adapter would be perfect if it was just a few hundredths of a inch longer so it would index on the barrel shoulder. When I tightened the SilencerCo adapter down, it started taking a sliver off the barrel thread. SilencerCo says that it's supposed to index off the front of the barrel because that's what S&W told them. But then you're left with the option of damaging the threads, or risking a baffle strike because the adapter wasn't screwed on tight enough.

It's a shame that in 2015 - gun accessories still don't work right for some of us.

I've already put mine (EWK & Sparrow) away after cleaning, but I'll have a look myself at the o-ring and report back. I'd like to think that if there is a problem, it can be converted to constructive feedback for EWK, and they would resolve it.

Smith & Wesson M&P 22 Compact Thread Adapter For Sparrow Blued - $23.00 : EWK Arms

Can't vouch for them at all, but they have the Sparrow thread adapter, blued, with thread protector for $23. $3/$6 for USPS standard/priority. The non Sparrow version is $22. I doubt the thread protector includes o-ring engagement.

I purchased one of these (EWK/ sparrow specific), and no the protector does not have the o-ring. That was my main complaint, as the protector worked loose in one session, and had to be chased down. That is a weakness.

As I understand it, the protector itself never has an o-ring. It has an o-ring "engagement."

sdl74,

Dragged out the hardware, disassembled the sparrow, got out the flashlight.

The EWK (sparrow specific) adapter threads don't hit the o-ring, which has no damage, but you are correct, it is not particularly snug.

You've challenged me now to buy the proper tool and measure. We'll see as the week progresses

But, I will thank you for bringing this out. Why? I have two other .22s that this will be used with. The adapter provided for one does not have the shoulder, so have ordered the silencerco version for that. Expensive little chunks of metal. Your question kept me from accidentally tearing up the o-ring.

The 10/22 is the other. In looking at this, I discovered the same issue, and explains the un-mentioned spacer in the Sparrow box. But it seems that one won't be the correct thickness, so more research in order.

So, after I settled down from the aggravation of having to buy even more parts and tools for something that should have been easy, I decided I should offer a thank-you for the research.

 

[hoc9sw]

As I understand it, the protector itself never has an o-ring. It has an o-ring "engagement."

That is going to require a little more explanation. There is nothing in the protector to engage anything other than the threads. It shakes loose easily.

 

[WilliamG]

That is going to require a little more explanation. There is nothing in the protector to engage anything other than the threads. It shakes loose easily.

I'm a bit confused. The thread protector comes off the thread adapter? Are we using the correct terminology here? The thread adapter is the piece that screws onto the barrel. The thread protector is the "ribbed" piece that screws onto the thread adapter.

I just want to make sure we're on the same page here. To me it sounds like you're saying the EWK thread protector shakes off the EWK thread adapter (i.e. when shooting un-suppressed).

FYI, I'm not surprised anything works itself loose. I have a Gemtech adapter on my M&P .22 FS, coupled with a Spectre II, and I have to tighten the suppressor down after every magazine. Gotta love that...
