M&P 22 Compact Threaded Barrel Question?

I just made an hour and a half drive to pick up the gun only to realize it has a threaded barrel which I don't want and I'm not even sure it is legal in MA. I called S&W and they won't sell me and have no plans to make barrels available for the 22 compact. I just don't like the way it looks hanging out the end of the gun. I was wondering if anyone had any thoughts on ths? Can I send the barrel somewhere and get it cut?

Thanks,

Phil

Screw a comp on that barrel then it will look cool.

Can you tell me the model number of the one you have? I want to order one with the threaded barrel out the end, so I don't need the adapter for my suppressor.

It came with a cap but I don't like the look

10199 is the one with the threads and cap.

Thanks for the info.

I had the same reaction when I bought mine (off the internet), I didn't like removing the cap every time to clean it. I ended up trading the gun but since have seen cap protectors, size 1/2 x 28, that I wish I had tried. I saw them on Amazon, around $15.

All M&P22 Compacts have threaded barrels.

The only difference is, one is flush with the end of the slide, the other extends (which you have).

You can probably just post up in the classifieds and swap barrels with someone who has the shorter threaded-but-not-extended barrel.

I might even consider that trade, as I'm indifferent to either look.

If I remember right, the thread on the end of the barrel is not 12x28. That is why you need a suppressor adapter to use 12x28 threaded suppressors.

Does anyone know the thread pattern on the extended version?

3/8x24. I have looked high and low for a thread protector in this size with no practical luck.

My extended version included the suppressor adapter.

Any competent gunsmith with a lathe can make you a thread protector for your .22. Now finding a smith who will undertake the thirty minute project is another thing altogether.

That is the adapter itself with a protector in 1/2x28 thread. What folks are looking for is just the thread protector in 3/8x24 thread.

Correct. People are losing the bubble on this.

All S&W M&P22 Compact barrels are threaded. All of them. The first one introduced had a "cap" threaded on over the threads that looked just like the end of a normal barrel. It is the same diameter as the rest of the barrel, albeit with a slight "bulge" to act as as sort of a bushing for slide lockup. The slide can be removed with this cap in place. In fact, if you didn't look for it, you might not notice the barrel is threaded. Here's a picture of the barrel with the cap very slightly unscrewed.



Another picture, screwed on tight:



And here it is removed.



This is pretty common, and the same way guns like the GSG 1911 .22 and P22 are done. With this model (the first one I bought), I had to unscrew the cap and purchase a suppressor adapter that threaded onto the barrel. The standard thread for a suppressor is 1/2"-28, and that is too large to fit through the hole in the slide for the barrel, not to mention the shoulder provided for the can to index against. Here's what the adapter looks like:



Here's a comparison of the factory "cap" (top) and a suppressor adapter (bottom):



Notice that the suppressor threads are exposed. To protect those, you use a 1/2"-28 thread protector. It either comes with the adapter or you buy it. That's what people are advertising when they say 1/2"x28 thread protector on Amazon, etc. It's a little ring, usually knurled, and with the adapter and thread protector in place, it looks like this:



Once that adapter gets screwed onto the barrel, there's no way it will go back through the slide. Since you have to move the slide forward over the end of the barrel in a fixed barrel gun to remove it, you see the need to remove the adapter if you want to, say, field strip the gun for cleaning.

Since I bought on of the "original" ones, I had to buy my own suppressor adapter (and wrench, but that's a whole other story), unscrew the cap, and replace it with the adapter. Some time later, S&W decided to offer their own, from-the-factory suppressor ready version (the second one I bought). It comes with the suppressor adapter in place of the "cap."

So....if you bought an "original," with the cap, you can remove the cap and replace it with a suppressor adapter, if you want. If you bought a "suppressor-ready" version, and want to get rid of the suppressor adapter (for whatever reason), you have to get a cap specifically designed for the M&P22 Compact. It has to fit the threads AND barrel profile of the Compact. Possible sources include 1) directly from S&W if they have and will sell them; 2) from a M&P 22 Compact user who replaced his with a suppressor adapter; 3) have one custom made by a gunsmith or someone handy with a lathe. Shouldn't really be too hard.

Great detailed reply and information.

So- - - - - has anybody found a thread protector FOR THE BARREL?????
I bought a suppressor ready because it was the only thing available at the time, but I would prefer to replace the adapter with a barrel thread cap.
I've called S&W and gotten different answers ranging from "They don't make them", "They are not available at this time", to "They are out of stock"

I guarantee you won't find one "on the shelf." No one is building these on spec. If S&W isn't going to stock them (or replace them) the best bet might be to try and get someone like EWK Arms (very responsive and capable) to run a small batch. If you're already set up to make adapters, the "factory" thread protector shouldn't be too hard.

Does the "suppressor ready" version come with a thread protector that protects the external threads on the adapter?

Yes. This picture is the suppressor-ready version of the gun, and you can see the knurled thread protector.

I'm indifferent to which barrel.

I have the original flush fit barrel, if anyone wants to swap for their suppressor ready version then shoot me a pm. We could just swap adapters but I'm a little afraid of trying to take off the adapter after hearing the horror stories.

For those of you who want to remove the suppressor adaptor and replace with a thread protector, you can order it from S&W. Part Number: 429020000

That looks like a .22, not a .22 Compact. Not having the larger .22, can't be of any help.
