Road to SHOT Show 2015: CZ-USA Scorpion EVO 3 S1

| January 15, 2015 | 7 Comments

When we asked you here, on Facebook, and on Reddit what you wanted us to cover at SHOT Show 2015, the most frequent answer was the Scorpion EVO 3 S1 from CZ-USA.


I am interested in the EVO 3 for the following reasons:

  1. It’s roughly the same length (according to published information) as an MP5K-DPW with the stock folded
  2. It’s retail is about half the price of the Atlantic Firearms AA-89 clone I wrote about earlier in 2014
  3. The firearm is ambidextrous, which is great for those of us that train to shoot from either side, and/or for those of you who are left-handed naturally
  4. The EVO 3 seems to be US civilian purchase friendly, with an arm brace option to help stabilize firing until your SBR NFA paperwork comes in
  5. I would really, really love to replace the KPOS NFA Glock enclosure with something robust and reliable.

That being said, I am worried about weight, as well as magazine availability and price. Glock magazines are plentiful and inexpensive, and the MAC 10 I purchased uses STEN magazines that were purchased for less than $4 each.

I’d also like to learn more about magazine options, as it seems like the EVO ships with a 20 round mag. There are 30-rounders sold by CZ, but I don’t have any confirmation that they’ll be sold in the US to civilians. The A1 version (full auto) has 30 rounders, but the A1 is only sold to law enforcement.

There isn’t a lot of information about accessories for the EVO (such as the pricing and availability of the brace and the stock). I also wonder if the pistol will ship the the grip as depicted in the photo. After training in the rain and snow several times I think the grip may need some “aftermarket adjustment” if sold as-is.

The Scorpion will be on the top of everyone’s list at SHOT Show this year. I hope to get some quiet time with the folks at CZ-USA to evaluate the Scorpion from the perspective of the vSBR / PDW civilian community.

    I don’t understand the hype for this thing at all. It’s a blowback pistol caliber carbine. It’s not particularly light (same weight, basically, as a Colt 9mm SMG). The mags are proprietary (albeit $20 a piece, or so I heard). I suppose the ergos look nice, and it’s tacticool, but it just doesn’t seem all that unique.

    Someone desperately needs to revive the Special Weapons SP-10 / PXP-10 concept – it was super-light due to the polymer receiver, used MP5 mags and mostly standard MP5K parts, and was roller-locked.

    • VanDerlin says:

      that sounds very interesting. However, the problem w/ any such gun that has a magazine well outside the grip is that the OAL/barrel length gets too long to conceal w/ a suppressor attached in a normal type bag.

      I would love to see a lightweight delayed blowback PDW type weapon w/ its magazine in the grip though. The Brugger & Thomet is this but they are some drawbacks there.

  2. VanDerlin says:

    Masterpiece Arms is now selling a Mac that takes Glock 9mm mags. They are even coming out w/ a mini version that has an all aluminum lower!

    Or, a super light short PDW type weapon might be a Beretta 92 w/ their 32 rd mags…

  3. VanDerlin says:

    I should add that the sig mpx that is coming out is gas operated rather than blow back. This, theoretically, affords less total weight and less action impulse. As it is the same size as this scorpian or an MP5 I think it is the way to go if you are into a weapon w/ magazine forward of the grip.

    • David says:

      The MPX is theoretically the best of all worlds, except for the small problem that Sig wants to charge roughly one million dollars a piece for it. The good news is that some insight into how they solved the 9mm rotating bolt problem might be good for the AR-15 9mm upper market, which has not had a lot of success with creating reliable 9mm DI or piston uppers.

      • VanderLin says:

        I have heard that common 9mm ammo is rather durty, affordable FMJ I suppose, and it is hard to keep a gas operated 9mm running w/o frequent cleaning of the gas tube or something. Seems strange that this is only the case w/ 9mm and not other pistol chamberings…

        Whtat is the rotating bolt problem w/ 9mm?
