This pistol is just about everything I could ask for. I was slightly weary about getting a full auto pistol, but I thought I'd try it out. I just got it today, and for my first impression, I'm rather impressed. First off, I'm using propane with it, however tried it with green gas, and both perform wonderfully. I got this to rival my friend's KWA G18C. It's definitely got some weight to it, however it feels comfortable. I've read descriptions that say the lower frame is Polymer, however the manual states that it's ABS. I'm not 100% sure either way, however it's very durable. So yes, Don't be fooled by "Full metal", everything thats important is metal. The magazine holds 18 rounds when the BB's are fed right, if you are only holding 16-17, theres one out of place somewhere, which can be solved by simply shaking the mag so they settle correctly. The Range of this pistol isn't bad considering it doesn't have a tight bore barrel. This gun disassembles easily, and the hop up is easy to get to and change. Once the slide is off, theres a dial on the hop assembly, thats it. No ant-sized hex-wrenches or anything. When firing on full auto, it takes a little practice to control and be accurate with, but its not impossible. Overall, I definitely recommend this gun. FPS is around 300ish.
-All metal slide and internals
-Paint on the cover of the top part of the slide will not rub off like on most GBB pistols
-Greatly constructed lower frame
-Comfortable to use
-Top part of the magazine that holds BB in place is plastic (I've seen this to be the first to break on many Gas pistols)
-Not holding this against the gun, however the case It was shipped in was cracked and split upon arrival
