I recently purchased a DW 22 caliber on the small frame. Looks just like the 357 which I purchased way back in 1984. This gun came without a barrel so I purchased one off of Gun Broker (barrel only, no shroud ) Hoping to use one of my 357 shrouds. That is not the problem. The problem is that this 22 barrel, which appears to be official DW manufacture, does NOT fit the pistol. The diameter of the pistol is about 25 thousands too small to accept this barrel. This 22 barrel threads right into my 357's (both of them) but will not go into the DW 22. Then I noticed that the serial number on the 22 is about 3,500. Did they do some thing in the dark ages and change the diamter and threads?? Checked the threads and it is roughly 40 threads per inch, but not exactly. It is not 38 TPI and it is not 44 TPI. Is this thing metric??? This is making me crazy, any help appreciated, Thanks. LG

Lonegunman, good morning and 
to the 
. Sorry your first post is a problem with a DW. As far as I know DW made the barrels so they would not screw into the wrong frame, i.e. the diameter / threads would not allow you to put a .22 barrel onto a .357 frame and try to shoot it. You might call the seller of the barrel and ask him about it or even better call DW in Norwich. They would have the specs for sure. If a get a chance I'll try my .22 and see what the fit on a 357 is.

Welcome aboard lonegunman, To bad you are having problems. I had a silly thought, probably not your problem but worth mentioning. Did you try both ends of the barrel? I know it sounds obvious but we all have silly moments at times. I have them most of the time.
The muzzle end of the barrel is the same as all other small frames I believe. Anyway good luck and welcome to the nut house.

Welcome!.... Seems like you have a unique problem there. A 22 barrel should never screw into a 357 frame--too much liability if someone touched off a 357 into a 22 barrel 
. Keep us posted, I'd like to hear the end of this one.

aboard, glad to have ya!
A couple questions come to mind, when reading your post & pardon me if they're blatantly obvious.
The barrel you bought was advertised as a .22, have you actually stuck a .22 bullet in the end, to make sure that's the size it actually is? The bullet should be just a touch larger than the barrel opening.
Since you bought the gun minus barrel, is there a chance that someone may have put a .22 cylinder on a .357 frame? In othe words, is the firing pin an offset rimfire style firing pin?
I wanted to eliminate the most basic questions, to hopefully help you out. Dan Wesson did thread the revolver frames differently, so the wrong barrel couldn't be accidentally installed & fired, as Shoot said. I guess that if everything does check out & is supposed to be correct for each other, it's always possible that the barrel was threaded incorrectly from the factory...to a .357 size. Does it look like it's ever been used & fired?

Welcome first of all to the great and powerful . I will share a weird but similar experience. I bought a used "414SM" barrel off GB quite awhile ago, but it would not even enter the threads of the frame of either my 41 mag or the 414SM. I sent it back to CZ and they had to rethread it, now it fits. Why you may ask 
No idea. but it was the correct caliber barrel. If the cost for the barrel was cheap enough you could do the same if it is justified.

Thanks to everyone for the input.
Yes, the barrel is threaded the same on both ends.
Yes, the barrel is a 22.
Yes, the frame is a 22 Rimfire
Yes the barrel goes right onto the 357 frames as if it were made to fit them.
No, can't find any reason why the DW 22 frame is smaller.
Elected not to bother with the CZ / DW folks as having them turn the barrel, with shipping could be a bit pricey so went with a local guy.
Took this mess to my gun smith. He measured and confirmed that the barrel was 0.025 to large in diameter. Over the threads right now it is about 0.525 inches. The thread count is roughly 40 threads per inch. That being the case the thread depth is 0.014. He will cut the barrel down in the lathe, taking off most of the existing threads, ( at 0.0125 per side of the barrel ) then he will simply cut the current threads deeper. He doesn't anticipate any problems. Will let you know when it is completed, but it looks like a done deal.
This barrel is 6 inches and I will use a shroud from the 357; should work fine.
I currently have 2in- 4 in -6in- 8 in -12 in and a 16 inch barrel for the pari of 357' frames.
Since I already have a 16 inch 357, it seemed only reasonable to have a 16 inch 22, so I am going to have a Ruger 10-22 barrel cut down and threaded to fit the DW 22 frame. Won't bother with the shroud, will just screw it on. Might mount a red dot on the barrel itself.
Looking forward to that I thought that with so much barrel, I might like to shoot a bit longer distance, so I have asked the gun smith to cut ONE of the chambers open to accomodate a 22 Win Mag. That will give me 5 chambers of Long Rifle with the 6th shot in Magnum. Generally I only shoot 5 rounds at a time in a revolver anyway. Even with the 6 inch barrel, I can see where having one chamber loaded as a magnum could come in handy for those extra long range shots; especially for small game hunting.
I have a chronograph so I will take some measuremnts, when I get it going.
Thanks again for all of your support.

I'm glad you got it figured out. It sounds like you're building an interesting project, definitely let us know how it goes.

You might want to consider a Marlin 60 (or similiar) barrel. I think they are more accurate, plus they have a nicer profile. I like the 22 mag idea.

Lonegunman, wouldn't you need the shroud to secure the barrel in place?

You screw them on just like any other gun (except DW). Of course you need to keep facing the threads back until you get the proper cylinder gap--then you just crank her on with a barrel vise !
My plan for this setup is to thread the barrel long, then use an external nut in front of the frame (like a savage rifle). This all goes back to my plans for a pack rifle on a DW frame.

If your planning to pack the gun around, one of the light weight carbon graphite barrels from Magnum Research might be nice. http://www.magnumresearch.com/Browse.asp?Category=MagnumLite:RimFire+Barrels

Wow, look at that!
It sounds sorta like a hollowed out tent pole.
Seriously though, that does sound interesting. I'd like to see one of those in action...I wonder what sort of "barrel whip" problems there may be?
Being .22 & smaller, probably not a whole lot.

Interesting on the .22LR/.22 Mag combo cylinder...I would be concerned about someone using it that didn't know anything about the conversion, and putting a .22LR in the .22 mag spot...Just something to keep in mind!!!

I've done that before--perfectly safe. They make a nice "pop" when they go off. Kind of like running the 9mm n my 40 S&W
