S&W M&P 10MM Barrel

[Johnch]

I bought a S&W M&P 10mm
LOUD sounds can cause my Migraines to flair up :cry:
So I do my best to control noise when I can

I know it is sort of a new pistol
I did some searches and couldn't find any yet

But has anyone seen a extended threaded S&W M&P 10mm barrel listed yet ?

Thanks
John
