M&P 9 Shield Threaded Barrel, New From Silencerco

Silencerco has rolled out yet another threaded barrel for a popular pistol, this time for the M&P 9 Shield. The Glock 43 barrel proved to be rather popular with owners of the single stack 9mm, I expect the Shield version to be no less popular. Interestingly Silencerco decided to not include a piston with this model of barrel like the Glock 43.

When I reached out to Silencerco about them not including a piston they told me that because the Glock 43 uses a special piston they include it with the barrel. The Shield will take the standard 1/2x28mm piston standard on just about every 9mm threaded barrel on the planet.

The new barrel with feature a 1:10 twist rate and be 3.65″ in length, perfectly suited for the M&P 9 Shield. The 416R Stainless barrels are finished with the same Black Nitride coating that the rest of their barrels are done with, so we know that the barrels are going to be rather resilient to wear.

The barrels are available now in Silencerco’s webstore and appear to be shipping. If you have a need for a single stack gun to be suppressed it would be hard to beat this combo. I think if it were paired with an Omega 9k it might even be concealable …. maybe.

    “If you have a need to suppress your single stack gun”.

    More like, if you shoot your single stack at the gun range and want to use your expensive sexy suppressor….

    For $220, I’ll wait a bit for the Chinese clones to force the price of these down then will purchase one…

      You really are salty.

    K, as a non-NFA never shot or handled a silencer plebian, what is this piston the article refers to?

    • Daniel

      It’s what mates the Suppressor to the host weapons threaded barrel. The equivalent of adding fries with that. Typically when you get a Suppressor you still have to buy a piston to attach it to a barrel and then depending on what type of barrel (fixed rifle/moving pistol/semi auto rifle) you still need a spacer to cycle properly.

    I understand the reasoning for machinability but 416 is not the best material for barrels or any pressure vessel for that matter. I would have liked to see 410 used instead.

    …so why would you put a suppressor on a CHL/CCW gun…?

    • Harry’s Holsters

      Because it’d make a cool little package to take to the range! Also a great companion for watching action movies when unloaded and all safety procedures followed.

  • MrPotatoHead

    That’s a lot of cheddar for a threaded barrel. More than half of what I paid for my Shield.
