    PDW? B-but, it’s just a pistol with a brace!
    Do they want the ATF to notice or something?

    • JackRyan

      PDW isn’t legally defined. They can call it whatever they want, but yes, it is classified as a pistol. You could call a Glock 19 a PDW if your marketing dept wanted to.

  • Amsdorf

    This won’t end well.

    • BattleshipGrey

      If the price is right, it’ll end well for people in states that allow ( I hate to use that word) for NFA.

  • Nicks87

    Glockazines? +1

    • JumpIf NotZero

      Magpul Glockazines, good timing on their part. But I think overall it’s a few years too late. There is going to be quite a bit of 9mm carbine competition this year.

      • Nicks87

        I agree, MagPul shouldve hopped on to that band wagon a long time ago.

        *cough* palmetto state armory ones for 600 *cough*

  • echelon

    If companies were smart they’d pool their resources and file some sort of class action lawsuit or something against the ATF over the brace debacle.

    I just can’t see anyone buying these things now that you could potentially find yourself at the mercy of the King’s Justice for shouldering the freaking thing…

  • JumpIf NotZero

    Overall nice. But it appears to be blowback which in an AR platform I would expect all the issues of a typical 9mm AR. A lot of recoil compared to delayed designs, which you might not notice usually because of the extra weight but could be noticeable this being 5lbs, and I would expect more than desirable blowback unless their bolt/carrier is stupid heavy in which case see recoil again.

    Looks good, but I’m think this released in 2008 would have been much more unique.

    when they come out with a PCP-PDW in 10mm I’ll take notice

    • jason

      And make aftermarket extended mags for the 10mm as well!

  • Vitsaus

    Should have been made to take P226 magazines.

    • Nicks87

      Why? Because you have a P226? Makes sense.

  • Ed

    Hmm, I wonder how this will this compare with the Lone Wolf G9, the Thureon carbine, or the Just Right carbine, which all take glock magazines.

  • noguncontrol

    they should make one in 7.63 mauser or 7.62×25 tok.

  • HM

    Or you could just buy a Glock.
