New SilencerCo Threaded Barrels for Glock

In the latest addition to their #FightTheNoise campaign SilencerCo has expanded their line of threaded barrels. The two new additions are made for the Glock 22 and 23, both of which are .40 S&W pistols. The new barrels join a group of eight pistol barrels currently being offered for the Glock 43, 17, 19, 21, 17L, and 34, SIG Sauer P226, and HK VP9.

SilencerCo threaded barrels are made of 416R stainless steel. That particular steel is well-suited for barrels in large part because it is considered to have good machinability. This allows it to be machined and lapped to a high finish to meet the exacting tolerances required of a precision barrel. The quality of the lapping process is extremely important when it comes to accuracy and high quality can only be achieved with the correct grade steel. 416R stainless steel gets it done with 10% chrome – which aids in corrosion resistance – and sulfur, which improves machinability. These are well-made barrels.

Shooting pistols with suppressors is both enjoyable and a good way to save your hearing. It’s also a nice plus to be able to talk to other shooters without yelling or removing or adjusting ear pro. Using larger caliber pistols suppressed is great for hunting as well; there’s just something about dropping a hog with a suppressed 10mm that’s absolutely awesome.

Wondering which SilencerCo suppressor to use with your Glock 22 or 23? Take a look at the Osprey 45.

    But are they polygonally rifled?

    • Edeco

      That was my first thought. Looks like conventional rifling in a cut away view in the ‘white paper’ on their website, but I don’t know how literally to take that.

      • Ambassador Vader

        Yea that’s probably going to hold back my money. those poly barrels are great.

  • TheNotoriousIUD

    Wonder if anyone has considered a flash suppressor for handguns to utilize quick release system for a can.

    • BattleshipGrey

      I’ve seen Berettas with a slightly longer barrel with groves on both sides for quick detach.

      • TheNotoriousIUD

        Very cool.
        I needs one.

      • Menger40

        Neat. What’s that weird ambidextrous lever that comes to the front of the trigger guard?

        • TheNotoriousIUD

          Yeah I was wondering too.
          Looks like some kind of slide lock.

          • Pete M

            Pretty sure it’s exactly that. Super quiet single shot.

          • TheNotoriousIUD

            It doesn’t damage the gun when you prevent the slide from actuating?

        • BattleshipGrey

          I wonder if it’s for loads that won’t fully cycle, so perhaps it makes it a single shot.

          • iksnilol

            Makes it a single shot for all loads.

        • It is definitely a slide-lock.

      • That appears to be one of the old Knight’s Armament “Snap-On” units from the late-1980s/early 1990s.

    • Theo Braunohler

      Well, you can use a 3 Lug adapter, but they only work with a fixed barrel. Some cans, like the Griffin Checkmate, have a 3 Lug system built in, but of course .22’s are always fixed barrel anyway.

  • john huscio

    No threaded 30s barrel. ?

  • Renegade

    Now where are those XD barrels they have been promising for 3 years?

    • Katie A

      SilencerCo’s marketing guy tells me not to give up hope, those are still coming. No timeline given though.

  • Pod

    I’m hoping for a GLOCK 30 threaded barrel soon…

  • mrsatyre

    Same barrel and steel from Lone Wolf for $105.
