Features
- 1/2x28 TPI Male Threads — Industry-standard rimfire muzzle threading accepts the vast majority of .22 LR suppressors, compensators, and muzzle devices on the market.
- Direct Factory Replacement — Swaps in place of the factory barrel nut on the SIG 1911-22 with no gunsmithing required.
- Simple Installation — Remove the original barrel nut with the factory-supplied wrench, then thread the adapter on in seconds.
- Steel Construction — Machined from solid steel for the strength and durability needed to anchor a suppressor or muzzle device.
- Suppressor Ready — Provides the correct host thread pitch for running a .22 LR sound suppressor on the 1911-22 platform.
- Compact, Low-Profile Design — Adds minimal length past the barrel so the pistol retains its 1911 lines and holster compatibility when nothing is attached.
- SIG 1911-22 Specific Fit — Machined to the M9x0.75 internal pitch used on the SIG Sauer 1911-22 .22 LR pistol.
- Special-Purpose Build — Purpose-designed adapter from United Defense, not a generic one-size-fits-all part.

Works great on my Sig 1911-22Been looking for this adapter for a while and finally found it here. Threaded right on my Sig 1911-22 no problem at all, took me maybe two minutes to install and it lined up PERFECT with zero wobble or play. I was a little nervous buying something like this online but it fit exactly like it should.
Exact fit for the Sig 1911-22 barrel

Simple Part That Just WorksNot much to say really, its a thread adapter and it does what its supposed to do. Screws on tight and lets me attach my 22 can to my 1911-22. Already have a couple hundred rounds through it with zero issues. .
Reasonably priced

Shooting suppressor-ready rounds has never been easier! Overall, definitely worth the investment for those looking to upgrade their 1911-22.
Perfect fit on pistol

Perfect fit, runs quiet nowHad the factory Sig adapter, lost it somewhere between the range and my car. Bought this as a cheap stopgap until I could find another factory one. This one is actually better. The factory adapter was aluminum, this is steel feels more substantial, threads seem cleaner. The length is perfect, doesn't stick out past the slide. Installation took 30 seconds, torqued it down, hasn't moved. Ran it with my Ruger Silent-SR, perfect alignment, no issues. The 1911-22 is already quiet, with a suppressor it's stupid quiet. The adapter doesn't affect reliability, still cycles everything including the cheap bulk ammo. For $11 I'm not bothering to replace the factory one if I find it. This works fine. Already bought a second for my range bag so I don't lose this one too.
