    "I bought this pistol about a year ago and have been using it quite often and it's good but has some flaws. First of all this thing SHOOTS HARD! On a normal day it shoots about 340, but on hot days it can get up to 380. People always let me know that it hurts. The magazine capacity is a great thing to have but the mags are so expensive, and have to be cleaned because if dirt gets in the double stack area the bbs jam up. The gas capacity on the mags is great, it is sort of a gas hog because it takes a lot to fill up a mag to the max but it lasts about 3 and a half mags. The gun itself is really accurate, I've hit people with it from upwards of 100 to 150 feet and the hop up is great. It's easy to take apart and clean, the blow back is crisp and clean. However, two months after I got it I noticed that the slide catch wore down and the mags would no longer lock back when I was out of bbs, but for me it wasn't that big of a deal. Just recently the front sight fell out because it just slides in on the front, but before it would slide over and throw the alignment on my sights off. What I would recommend is just to glue the sight in place so you don't loose it. YOU CAN BUY REPLACEMENT PARTS ON KWA'S WEBSITE. This is the link to the slide catch,
    Overall it does its job extremely well.

    Great FPS
    Ammo Capacity 27 (28 if there's one in the chamber)
    Gas Capacity
    Crisp blow back
    Good Cycling rate

    Slide catch wears down and the gun no longer locks back when empty
    Front sight falls off
    Mags jam when dirty
    Mags are EXPENSIVE!!!!

    "This gun is great. Comfortable to hold, very light unloaded, hop up carries .25s forever (BB travels ~200 feet level, though its not super accurate because, well, it's still a pistol with combat sights). The magazine is pretty much a hi-cap compared to other pistol mags at 28+1 rounds, and they are very sturdy magazines. The top where the BBs feed is metal, so you can let the follower go from the bottom and it won't break like other pistol mags with plastic tops. Using propane, I can get about 2 and a half mags of BBs on one fill. The only problem I've had is sometimes when I empty a magazine and the slide is locked back, it'll slide forward with the insertion of the next magazine. All in all this gun is a bit pricey but well worth it. Personally I'm gonna try to get an over-under rail mount and throw a red-dot on it to imitate my trusty sidearm in Battlefield 4, and get metal outer barrel of some sort.

    Very accurate
    Comfortable to hold
    Magazines are very sturdy
    Good magazine capacity

    Slide problems when loading a new mag
    Front sight seems easy to slide out

    "Mixed bag of HK fanboyisms

    Im not sure if I love this gun for how it performs, or how sexy it can be.

    In the hand, this gun is comfortable for most hand sizes, it's MP7/USP push-down mag release is also very nice to use and is a great relief for those who are used to button mag releases.
    This gun is as attractive as it is fun to shoot. I would recommend purchasing detonator steel parts along with this gun to give it it's full aesthetic potential. As soon as you buy the gun, you are going to want to replace the outer barrel anyway.
    The gun is durable, as long as you don't smash giant blocks of ice with the bottom of the mag when you're bored (which broke one of my mag baseplates). Another gripe I have on the external quality is how easy I managed to chip my frame by accidentally dropping it on concrete, I expect a new frame shipped to me as soon as they come back in stock (which is difficult considering the recent KWA-H&K licensing snafu).
    This gun is a performer. It fires a constant approx. 330 FPS when you feed it GOOD gas, and is extremely efficient considering how it managed to last about 2 mags of bb's on one five second gas charge in BELOW FREEZING weather. I tested this by completely burying the gun in 2 feet of snow for five minutes. The FPS didn't drop much either.
    If I were to complain, all of my mental stress is on the sights. The sights are good sights, but their durability is VFC HK416 GBBR bolt durability. My front sight fell off a month after I purchased it, and the pre-administered blue locktite for the back sight (which is screwed in) doesn't seem to keep the screw from partially unthreading itself, which makes the sight wobbly. Parts for this gun are also extremely hard to find. If you get this with a threaded barrel, good luck finding a holster (I still haven't even found one).

    Overall, this gun is a winner if you get new sights and detonator parts, which don't come cheap. If you have the money or the time and effort to bring this gun to it's full potential, this is an amazing replacement to your current green-gas pistol.
