Hands on With the HK USC

The HK USC (semi auto version of the UMP) is coming back to the US market in very limited numbers. With an MSRP of $1500 it’s not exactly a cheap gun but in the HK world the USC is a pretty good deal.

HK has one on display at NRA show. I got to check it out for a few minutes. It is surprisingly light weight, only 2.72 Kg that’s 5.9 pounds in American.

The direct blowback .45 carbine comes with a 10 round magazine, and no threaded barrel. I was surprised how plasticy it felt. I know its a polymer gun but a lot of polymer guns don’t feel like plastic. I would imagine that the USC sells out fairly quickly when they are available later this year. Maybe HK doesn’t hate us after all.

    Threaded barrel seems like an obvious feature to include. added mfg cost is about 11 cents and additional MSRP has gotta be at least $11.

  2. avatar jwtaylor says:

    The only value of this gun is to do a USC to UMP conversion.

    1. avatar MyName says:

      University of Southern California to University of Malaysia Pahan? Odd transfer but most credits should apply.

    2. avatar ColdNorth says:

      Up here in Canada, MP5s are prohib, but the USC/UMP is non-restricted. Makes for a nice plinker, and another PCC alternative for shooters up here.

      1. avatar anonymoose says:

        May as well have 5 rounds of .45 than 5 rounds of 9×19 anyway.

      2. avatar Mark says:

        I wonder: What is the French Canadian word for “plinking”?

  3. avatar MisterFurious says:

    This gun could be so great; thread the barrel, folding stock, mags that actually hold a few rounds…but nope, still the same gun from the ban years.

    1. avatar SigLifeSailor says:

      To be fair, that’s more due to German and American export and import laws and their interplay than any decision on H&K’s part. That being said, I agree that it’s a shame that it’s only coming in as a compliant gun.

    2. avatar Dan the Man says:

      You either forgot about, or don’t know about, the 1989 assault rifle import ban signed and promoted by president George “no new gun laws” Bush the 1st (who voted for Hillary Clinton if you didn’t know). This gun is made in Germany and imported so this is the ONLY way it can be imported. If HK would make it here, then that would be another story. The 1994 domestic assault weapons ban expired in 2004, the import assault rifle ban did not.

  4. avatar New Continental Army says:

    1500$ for that? Yeah. Ok.

  5. avatar Moltar says:

    Ugh!!! So much potential wasted!!! Somebody please start makin an excitin AFFORDABLE pistol caliber carbine. Sure the thompsons are awesome even though they’re just semi autos and non sbrs and super expensive but they are at least a little exciting.
    I’d love to see a PCC version MP40, PPSH, or really anything other than a PCC AR, neutered UMP, Hi Point, or Ruger.

      cz scorpion evo
      sig mpx
      aero survival rifle (can screw it apart! takes glock mags)
      Kel tec sub 2000 (not a fan, took modification on my part to make it work right, but it is different)

      I can only speak for what I’ve shot and owned… they should fit what you are looking for 🙂

      1. avatar Moltar says:

        Scorpion is less than an Auto Ordnance Tommy gun, shockingly (well at least it is to me) the Sig costs more. Still both aren’t what I’d term affordable for what they are YMMV. For that same let’s say $900 for the Scorpion I can get a good number of full size semi automatic rifles that shoot actual rifle calibers and fill a need in my arsenal.

        Aero is a neat little gun but I can never find it in stock anywhere long enough to order it on payday.

        Kel Tec- love their oddball stuff but that’s a hard pass from me. lovely design but all the reliability of those diesel engines GM based off the Olds 350.

        Sig price: $1699.99 (https://www.budsgunshop.com/catalog/index.php?cPath=2084_36_397&filter_id=51&caliber_id=10000837)

        Scorpion price: $898.00 (https://www.budsgunshop.com/catalog/index.php?cPath=2084_36_63_971&filter_id=407&caliber_id=10000837)

        Thompson price: $1260.00 (https://www.budsgunshop.com/catalog/product_info.php/cPath/2084_36_440/products_id/41635/Thompson+45+ACP+Deluxe+50%2FRound%2F20%2FRound+Magazine+Walnut+%26+B)

      The PC9 is like $500…? How is that not affordable?

      1. avatar Moltar says:

        affordable yes, exciting (AKA looks cool or at least interesting) no.

        1. avatar Setnakhte says:

          A Beretta CX4 then?

  6. avatar Moltar's Ex says:


    Look around Butter Cup.
    Exciting PCCs (and conversions) abound.
    Come down from yer high horse for a better look.

    1. avatar Moltar says:

      so glad we got divorced also the paperwork says no contact for a reason Sheila. You still owe me child support too.

  7. avatar Muhammad says:

    That big ass HK logo is what’s adding about $700 to this price.

  8. avatar Paul Mcmichael says:

    Tons of experience with the MP-5. Not so much with the UMP. First saw one when working with the Charlotte, NC SWAT team at Katrina. Yawn. Boring weapon.

    1. avatar anonymoose says:

      Well, they designed it to be a cheaper, more “conventional” replacement for the MP5, but also to reliably use .40 and .45 when a lot of American cops and American spec ops units (respectively) were enamored with those rounds (unlike the MP5/10 and MP5/40 which cracked after long-term use).

  9. avatar strych9 says:

    The street price will prolly be a few bills lower than MSRP.

    The UMP is a good gun, so I’d take one of these to SBR/thread/slap an Osprey on for sure.

  10. avatar AZgunner says:

    That would be awesome without the excessively long barrel and non folding stock. Make it a pistol with a short threaded barrel and folding “brace” and watch how quickly they would sell.

    1. avatar Tom in Oregon says:


    2. avatar Hannibal says:

      Yup. Anyone who wants this gun (as opposed to a cheaper but still excellent carbine) wants it for the appeal of basically having a UMP. Might as well embrace it, and a pistol is the best way to do that.

  11. avatar Your Dad says:

    Yes, but does it take Glock mags?!?

    1. avatar Greg says:

      Yes, just push hard when you insert the mag.

    2. avatar Hannibal says:

      only if you put them in backwards

  12. avatar Mike Hawkizard says:

    Better to get an omega upper receiver and a demilled ump parts kit to make your own.

  13. avatar Chris says:

    I had a 1st gen USC(light grey), it was a fun Carbine. I sold it for more than I bought it for when HK stopped selling them here. I should of held on to it.

    1. avatar Greg says:

      Same here really liked mine. Had to sell mine too they hold their value.
      You can get 20 round mags from promag though they can be hit or miss.

  14. avatar Donkey Lips says:

    Thumbhole stock….neutered 10rd mag… non-threaded barrel.

    No, HK still surely hates us. And guess what? I still hate them 8D

    Not that HK has innovated anything decent in, um… the MP5? That’s all I got.

  15. avatar ironicatbest says:

    Oh no!!! Another Evil Black AsSalt rifle, quick torch it before it reproduces

  16. avatar billy-bob says:

    Why pay $1500? If you just want an ugly PCC in .45 with 10 round mags, get a Hi Point and a lifetime guarantee.

  17. avatar Hinshelworld says:

    Let’s see…

    Overpriced, 20 year out of date ban era configuration, typical cheesy HK plastic, not an MP5.

    They still hate us.

  18. avatar Docduracoat says:

    As others have said, the stock is ugly and the barrel is too long
    You did not mention if it was possible to remove the stock and replace it with some aftermarket folding brace
    After you get your stamp to SBR it, you obviously chopp that barrel, thread it, and slap A suppressor on it
    I love my Scorpion and I like my buddy’s Zenit MP 5 clone
    A PCC in .45 sounds nice

    1. avatar jwtaylor says:

      “You did not mention if it was possible to remove the stock and replace it with some aftermarket folding brace”
      It is possible, it is not particularly simple. The stock is integral to the lower. For those used to AR “gunsmithing”, it is quite a bit more involved. Google “USC to UMP conversion”, and you’ll find three major ways of doing it, each with similar levels of functionality, but different levels of finish.
      Done right, the end result is exceptional, functionally identical and cosmetically extremely similar to the UMP. It’s one of my favorite guns of all time. It shoots about 4 inch groups at a hundred yards and if there is an upper limit to its reliability, I haven’t found it yet. I routinely go 2,000 rounds at at a time through mine, and all suppressed.
      Heck, I’ll just do a review on the USC to UMP conversion.

      1. avatar TheUnspoken says:

        I do like the USC to UMP conversion, though definitely not a cheap gun. You need a stock block or otherwise fuse/plastic weld a UMP receiver stub. HK has been importing a lot of ban compliant/California models in the pistol side of things, USP experts, gray model, elites, I wonder if these USC guns are compliant with any states that would otherwise ban via AWB? With the old two feature or national bans they could be compliant, but a lot of slave states have gone more restrictive and I don’t think you could get a USC in California, New York, Conn, etc.

        I don’t have a problem with HK selling this, though they are basically just importing a limited number of the same old gun, not a new gun or configuration. I know Michael’s Machines previously was able to import some unmarked USC receivers from HK as “stripped receiver/firearms” and thus build pistols from them. It would seem HK USA could likely do the same, slap braces on them, etc.

        My real question is… What of the HK USA factory in Georgia? Maybe restarting some mr556a1 builds but I don’t think they built the factory for that alone. I thought they declared it would be for the civilian market, but I haven’t seen them using it for any products yet, vp9 is still all German, sp5k, USC. Perhaps they ended up doing csass and various Marine Corp 416/m27 variants, but I am still expecting something distinctly USA.

      2. avatar Greg says:

        Hera arms makes bolt on parts to use AR or ACR stock. I tested promag 15 an 20 rounders with no issues. Save yourself money folks.
        They are selling cheaper than MSRP.

  19. avatar Butcher says:

    MAC did a hit job on this weapon. Guess he didn’t get paid enough for the review.
    Dude is a total POSER! Marine SF= Glorified Security Guard.
