Try GSG (German Sport Guns).
It's owned by SIG's parent company according to the web and they make .22LR clones of the P226. You'd have to check with them as to compatibility though.
Have you tried contacting SIG customer service yet?
They may be able to help you out too.

 

This might be difficult. Sig discontinued the .22LR conversion kits some years ago, and even when they were in production it was before the suppressor boom (no pun intended) of recent years so threaded barrels weren’t as common as today. May want to call BarSto and see if they can do a custom one-off for you. Good luck and let us know if you find one.

 

Yeah that might be hard to find but you can probably find one. Might keep an eye on gun broker or you might get lucky at a local gun show.

 

Big difference, whether you are talking a Sig branded P226, in .22 rimfire, or the "Mosquito"/"Firefly" of German Sport Gun heritage, as their parts are not interchangeable.

Did recently notice a Gun Broker vendor advertising these... Sig Sauer P220 22 LR Threaded Barrel BBL-220-22-T - Shotgun Barrels at GunBroker.com : 1071251969 which with the original rimfire Barrel could be converted, by swapping the underlug.

 

Willard, pardon my ignorance. What do you mean "swapping the underlug"? Do you mean knocking out the lug pins on the P220x.22 bbl and this P226x.22 non-threaded bbl and swapping the lug?

 

Good luck. I've been looking for a couple of years. If you find a source...

 

There are some threads here, showing the difference between the P220, P226, and P229 Barrels used in the Sig Conversion units. I believe this is it... New Information on the p series 22 LR Slides/conversion kits from Sig Custom Shop | SIG Talk

.22lr Conversion For 9mm P229 | SIG Talk

 

Just ordered the threaded P220 barrel. Will swap the lug with my .22 P226 barrel and post results here. Thanks for the great info. I'd considered selling my P226 .22 conversion. I can practically buy a dedicated .22 for not much more than they sell for now.

 

Welcome from Tennessee and God bless you!

 

The P series 220,226,229 22LR barrels are identical.

P229 Guide Rod is longer thn the P220/226 rod.

The pinned lug is marked on the RH side for the platform/ barrel to mount it to.


Ruger MkI & MkII magazine latch system is superior to the MkIII or MkIV push button/1911 magazine release.

IF,a magazine rattles in the frame/receiver...you will have feed issues.

 

Someone had a threaded P226 .22LR barrel in the Marketplace recently but I noticed that it's now marked as SPF. I wish I had known that it might work in my P228/229 kit if I swapped the lug from the unthreaded barrel.

Here is what I received...

 

I wonder how much pressure goes on the lug. Is this a part that could be 3D printed?
My threaded barrel is scheduled to arrive today. Hopefully I'll get a chance to knock out the pins, swap lugs, and try it on the range before the holiday.

Being a rimfire likely not much pressure... and in the cases of these Barrels, being made for the P220, as I mentioned earlier, should you desire using one for a P226, or P229R, which are the same overall length, swapping the lug from the unthreaded original Barrel, is all that is necessary. Finding replacement tension pins would be the most logical step to take, to ensure proper fitting and attachment of the lugs, as they would be the weakest link, so to speak.

 

Welcome from Arizona. It really is a dry heat.

 

The Sig conversion kits and threaded barrel can be a challenge to locate. Ebay, Gun Broker and simular are the places to find one that is being sold as the kits are out of production. A 22LR threaded barrel is another highly sought after (rare find) I recently viewed a Sig 22LR threaded barrel for sale and was $999.99. It took myself over year to locate one for sale and was pricey.
