  • Realistic hammer movement
  • Semi-auto repeater

The Umarex H&K USP Blowback CO2 Pistol is an officially licensed replica of the H&K pistol, famed for its straightforward design and use among law enforcement or military.

As the name suggests, this H&K USB features a full, responsive blowback of its metal slide each time a shot is fired.  With Umarex's fine attention to details, the USB uses a trigger that can fire in single or double-action to keep your shooting sessions as realistic as possible.

To get started, load up the 16rd BB magazine, drop in a single 12-gram CO2 cartridge and commence slinging lead at 325 fps downrange. Each includes fixed white-dot sights and an accessory rail for helping you put shots on target fast.

If you affordable CO2 blowback pistol built for dropping cans and peppering paper targets, choose H&K USB and see what your shooting sessions have been missing.

Verified Purchase

Things I liked: First of all I didn't use this item.. i don't know yet but just from looking at it out of the package I think it's a well put together item.. it's nice.. definitely an original I actually like it.. it's just too cold to test it out..

Things I would have changed: I would love for it to let you know when it's the last it doesn't stay lock on last shot and a hammer in the rear..that's all

What others should know: It seems to be a nice piece.. but like I said I haven't actually tested it yet.. but I did do an out of the box check.. and that definitely feels like a keeper

Things I liked: The function of this pistol has been nearly flawless and what malfunctions I experienced turned out to be caused by an issue I will address below. It has nice heft, a solid feel and the ergonomic design of this pistol make it comfortable in handling. The magazine is constructed like a tank, very solid. Despite not having a hold back feature for the follower, I did not find it problematic to hold it back with the off hand while loading with the other. Yes, the spring is fairly stiff but I found it manageable and I could control the follower without issue. The piercing method is solid but a little practice is needed to properly align the threads of the piercing cap while managing to keep the hex wrench from protruding against the powerlet and pushing the cap out of engagement while starting the threads.The trigger is consistent, of a good weight and it is easy to develop muscle memory for when it will break to help with consistent sight alignment. Recoil is robust, especially at first.

Things I would have changed: I would either re-enforce the forward area of the frame at the accessory rail or make the frame of metal. There are metal guides installed in it to provide endurance and dependability for slide engagement and travel during recoil but the accessory rail has no standard mounting groove or cross-slots to accommodate commonly used lasers or lights. The firearm version of this pistol has the same design and an adapter is available to convert this to a picatiny rail. I bought one of those and discovered it is not possible to install it firmly enough without flexing the forward area of the frame inward with the mounting hardware. This resulted in the malfunction mentioned above: the slide would bind in this area and fail to cycle properly. I discovered however that the Laser Max Spartan SPS can be mounted directly to the pistol frame without an adapter since its mounting method allows it to open up and be placed in the mounting groove and then tightened down without causing frame distortion.

What others should know: My pistol did not shoot to point of aim with the fixed sights, so a laser may be needed to remedy this. I found the pistol would shoot any brand of BB (11 various BB's were tested) to the same POI and all grouped well. One to avoid however is the MarksMan Premium BB. It is oversized at .177" and will not work in the .175" bore of many pistols but will jam solidly in the barrel (See my review of the MarksMan Premium BB). The MarksMan Laserhawk will work just fine. Of the 10 serviceable BB's I tested, group size ranged from a low of .667" to a high of 1.352". I shot 2 five shot groups at 6 yards with each ammo (standing free style, unsupported, two hand hold) and averaged the two groups. When I knew I had pulled a shot I took another to make up 5 well held shots. This pistol shot 6 of the 11 BB types into less than an inch. Groups of an entire magazine of the best ammo were under 2" counting all 18 shots of the group. Most of the 18 were much more closely grouped.

Things I liked: Very realistic looking and feeling, very aggressive stippling. Hefty and hand-filling. Spacious trigger-guard.

Things I would have changed: The BB magazine has no latching mechanism and the follower spring is very strong, so it is exceptionally hard to load BBs into the magazine. My magazine would not pierce any of the multiple CO2 cartridges I tried: a bunch of Crosmans, a Daisy, and an Umarex. The piercing pin made a significant dimple in each cartridge, but no piercing. That means the air gun has a zero for accuracy (couldn't hit the target at any distance), a zero for value for the money (non-firing prop guns shouldn't cost this much), and therefore a zero overall rating. Pyramyd Air's return service was excellent, however.

What others should know: If you can get yours to work, maybe it is an OK or even excellent air pistol. Mine was just a paperweight. And how much are these hard-to-load, won't-pierce-a-CO2-cartridge magazines as an accessory? Oh, and the pot metal used throughout is extremely soft, much more so than on air pistols made by other manufacturers.

    Field strippable? Thanks

  • John from USA asked:

    I see that in these stock photos, it does not show the warning message on the right side of the pistol, but in a video review I saw (five days old and done in North America) it did have the lettering. Is it safe to assume it does come with the unfortunate warning message?

    • Gregory from Canada:

      Now that PA is selling this gun, is the slide spoiled with WARNING text?

    • Tyler from USA:

      The warning is legally required. But where it will be located for certain, cannot be said until the production guns hit shelves
