Umarex H&K Licensed USP Full Size CO2 Gas Non-Blowback Airsoft Pistol (Color: Dark Earth)

"I just got this gun from another hobby store, so I can't tell how reliable it is, but I would like to point out that this is exactly the same as the black version.
As to performance, here's what I have found:
The gun is double action only, so the trigger is pretty long. However, it's a very smooth pull, so with practice you will get used to it. Accuracy is okay, I'm using .20 grams, and about one out of five shots curve left. This is due to the bad hop unit, which by the way, is NOT adjustable. Also, the bb drops pretty fast past about 50 ft, again due to the bad hop, but you can still hit things just fine up to 100 ft. Anything past that, and you lose to much fps. The handle on this gun is enormous, so if you have small hands, this is not the gun for you. The safety is similar to a 1911, but the mag release is a hard-to-reach paddle style type common to European designs. Overall an excelent pistol, and as long as you put some silicone oil on the valve and air seal, it should last a long time.

"i got this gun 6 months ago and its still going strong, this is a fantastic gun FOR THE PRICE. i highly recommend this gun for your first pistol or just a loaner.

pros
accuracy
gas efficiency

cons
trigger is SO long (but this is expected with a non blow back)
range (expected with a pistol)
no hop up
mags are heavy

"This is a great gun. It's even better in a carbine conversion kit I got off of umarex. This is a great CO2 beginner pistol that everyone can enjoy.

"This was my first airsoft pistol I got about a year ago except mine was in black but anyways this is a very good beginner pistol and it gets the job done if you don't want all that fancy a expensive blowback this is the gun for you it holds 16 rounds and has good fps (not sure how much it is exactly) the body construction is very good and is very durable.

"I bought this gun used from a guy at a flee market so the gun wasn't in the best shape when i got it. The mag really only holds 16 BBS not 26. Despite what the description says it is just a CO2 NON blow back gun, and as far as i can tell the hop up is not adjustable. After a while of use my safety does not really stay in safe mode when you pull the trigger, also after a while i have noticed that when you put a new CO2 cartridge in it leaks. But i really like the gun, you can get about 4-7 mags worth of shots off before you have to replace the cartridge and the gun has a very sturdy construction while not being to heavy. The gun shoots pretty accurately and shoots about 45-110 feet.

"Got this pistol as a backup. I'm not a fan of GBB pistols and I wanted something efficient on co2. You can get over 100 shots off one co2 cylinder. Replacement mags are abt $20. Requires a hex wrench to replace the co2 cylinder.

Magazines are a pain to reload, horrible design. You literally have to hold the magazine upside down and look up at the magazine to reload it. If you want to be able to reload on the field don't get this.

It's accurate, I can hit a paper plate at 75' consistently. Chronoed at 380.

Kinda recommended based on your style of play. As for me, I'm disappointed with it.
