M&P 22 Compact thread adapter for Sparrow

[Dghost]

I was wondering what thread adapter you guys are using for your suppressor, or in my case, the Sparrow.
I have an EWK adapter, but it seems like the transition from the barrel to the adapter isn't as smooth as the factory unit. When the slide comes forward, I can feel it hit the adapter. Over time, I would imagine it would start to wear on the aluminum slide.
Does anyone use the Silencerco adapter?
Thanks
