Heckler & Koch USP Blowback .177 BB Air Pistol

As a Replica, this H & K was spot on! The realistic feel and weight was a perfect Replica. The tacky grips are Excellent. The blowback is amazing, punchy, and snappy, with a very strong recoil spring that brings home the beast of a slide to a loud and crisp break. This chunky pistol has a very satisfying and delightful trigger that doesn't take much to fire. The air does most of the work, where in alot of other pistols, the trigger does the work in feeding the bb into the breach. I would have to give this gun a 5 star as far as a Replica air gun goes, to its real life counterpart.

Trigger and inner parts, sear. Rear to the gun, must be improved, materials are not strong enough for this beast of a gun. Blowback is so strong, along with its recoil spring on the guide rod, cant hold up, the things break on this gun. Its such a cool gun, its heartbreaking and so disappointing.

Strengthening the trigger assembly is a must, and a big cry out to Umarex to fix this trigger, as it is a bigtime FAIL in the manufacturing and design. It breaks and leaves the gun inoperable. Inner Materials used is some sort of Pewter, or just the cheapest tin metal on earth. It cant stand up to repeating firing for very long. The frame in the back that holds the guts to the hammer and operation, fails and cracks. I'm hoping I got a lemon, and my replacement will be a good one.

Maybe I got the USP version of a Winchester One-of-a-Thousand, but darn this thing is accurate. Very good fit & finish, grip has stippling very heavy like CZ P-07. Nice white-dot sights. Magazine drops easy. A crisp blow-back. Safety clicks in confidently (and can de-cock by pushing all the way down). Just a nice balanced, good shootin' pistol, especially for the price, hard to beat. Was really surprised how much I liked this my first time out (and continue to). Right out of the "box" this pistol sparked much joy!

The Achilles heel is in the magazine. That darn CO2 locking nut harder to thread than most, similar to XDM and M&P 40, which is not a good thing. It take patience, it's not a race. Try lining up the locking nut and then turning the magazine itself slowly until the thread catches. You get the hang of it after a while. The real issue now is finding spare mags(!), lucky to find one at a local vendor. The usual complaint about those UX heat-sealed clam-shell packaging. You have to take you life into your hands slicing open (not mention possibly marring your pistol!). Please UX adopt what SIG did and swtich to unsealed clam-shell inside a cardboard box ... or crazy idea, just a cardboard box!

Was on the fence about this pistol due to bad reviews for a long while, but price dropped and Bulleye Bucks calling, finally went for it, and so glad I did. Has shot to the top of my favorites! I'm an avid replica pistol collector, shooting on an indoor range at 15-20 ft. I've tried UX steel, Crosman Black Widows, Hornady, Copperhead BBs, and all shot well. Mine shoots slightly low, but windage is on target, tends to shoot better on 2nd magazine, once CO2 settles down. Overall, a very good POA to POI for a smooth-bore and non-adjustable sights.

What I liked: True to actual as a replica. Great accuracy. Great feel and shooting comfort.The blowback is wonderful and the realism could not be better. My 3 star rating is only because the pistol shoots so well. The H&K shoots low and a tad to the left, but if you compensate reasonably well it will put five shots together with little room to spare at 10 feet. My Caldwell crony stats were as follows for a 12 shot string: Hi velocity - 348 fps, Lo velocity - 338 fps, Range - 10. Average Velocity - 343.8 fps, SD - 3.05 fps, Variance - 3.18 fps. I have over 50 airgun BB pistols and the only one that comes even close is my Desert Eagle, but that's a pellet pistol. Easily met and surpassed spec.

The Magazine. It is a game-stopper. Really bad. Loading the BBs into the magazine is so hard that I vowed I probably would never use this airgun again, once I had tested it. Then there is the threaded cap to secure the air cylinder. I have several other BB pistols that use the same type of cylinder piercing and I have no trouble with them but THIS one I could not thread. I finally used a wire brush wheel to remove the black stuff on the threads of the cap but it did not make things easier. It took me about 20 minutes to finally get the cap screwed down tight and piercing the CO2 cylinder. Basically, the threaded cap sits so low into the handle that you can't hold it to thread it in without causing misalignment and you might even cross thread it by trying to use the allen wrench to thread it in. Very, very bad design

I am VERY disappointed in this replica. As a replica, it is totally 5 star. As a working replica, it is only 1 star due entirely to the unbelievably bad magazine. You must hold the follower with a very strong thumb during the entire attempt at loading the full capacity of the magazine. You must hold against a very strong spring while attempting to drop 15 BBs one at a time against a small opening left immediately in front of the spring. I don't have enough fingernails to do this many times in succession. I limited myself to loading 3 times for testing. I will not do it again. Count on dropping multiple BBs. I used two cylinders; one for the accuracy shooting test and a fresh one for the fps statistics. I wished I had only stuck with one cylinder, because threading a second cap for a fresh cartridge required another 20 minute struggle with the threaded cap. I can't believe that Umarex let this product out into the market with the really terrible magazine for an airgun this good.
