Heckler & Koch USP Blowback .177 BB Air Pistol

Low budget way to practice in the back yard. Look, feel, and opertion is very realistic. And it is fun. Seems to eat steel BBs, Dust Devil BBs, and even plastic BBs. Way better than expected shots per C02 cartridge. Blowback feature provides a reasonable tactile feel and lightens trigger pull.. Last shot slide lock feature is very nice.

Create a better spring lock for the mag. to make it easier to load. It has one but it does not work well and is difficult to engage. Lower the price of the mag. Would be nice to have a 2nd mag... but not at that price.

Keep ranges short or targets large to increase the enjoyment. It isn't a match grade pistol. Last shot slide lock may not work reliably if your trying to squeeze out that last bit of C02. The slide may not get pushed back far enough to engage the lock.

My favorite thing about this item was the 2 months that it worked without issues . First it was the screw that pushes the co2 . Then it was the follower getting stuck .after that it was the plastic striker that hits the air release valve when you squeeze the trigger .

I would change the cheap pot metal screw/plug that holds the co2 . It strips easily . Then I would change the follower. It is cheaply designed and is barely functional . Then I would usea different material with whole trigger mechanism it is also cheaply designed and when it fails , and it will renders the item useless .

This bb gun was an extreme let down . Out of the 5 or so months I had it i shot it on maybe 5 or 6 occasions no more than a hundred bbs each time. I know a refund or store credit is not an option due to the time I have had it . Not worth 115 bucks. Not worth 50 bucks. Hopefully the fine people here at pyramid will see my dillema notice how long I have been a customer and give me some kind of hope for a resolution in this matter.

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.
