A threaded barrel for my M&P 9mm Full size?

Not sure if I should just call S&W and ask their parts guys about the S&W Threaded barrel...or, get one from Storm Lake or a Storm lake distributor..

I'm looking for the same thing. Brownells stocks the Storm Lake threaded match barrels, but they're a bit spendy. I called KKM last week with the same question- they are currently re-tooling for the 9mm barrels, but should be up and running in a few weeks. They will be offering threading for their barrels once production is back up. Having seen how they perform in other platforms, they will be getting my money as soon as they are up and running.

I got my USP factory threaded online. For M&Ps looks like storm lake makes a bunch.

S&W makes one but as far as I know they only sell it with the gun just like the range kit M&P, I might be wrong though and they may sell it seperatly. I would get a Storm Lake barrerl if it were me though.
