I didn't get this gun from Airsoft GI, but I decided to write a review here anyways. This is my first GBB, and I love it. It is full metal, and has a very hefty feel. It gives you the impression that it's a gun of good quality, not just some sports store CO2 gun. It's also very efficient; I can get about 1-2.5 clips off with a single load of green gas. Accuracy is good for a pistol, right out of the box I could hit a 6" target from about 50 feet (That's EYEBALLING folks, I don't have the exact measurements.) The kick is beautiful, but firing it one-handed can be a bit of an issue. The only real problem I've found so far is that the barrel moves around significantly when the slide is back, but from what I've read this happens with a lot of KWA's GBBs.
-Hefty Hefty HEFTY
-Looks beyond awesome.
-Kicks back. A LOT.
-Freakin' loud, bro!
-Ergonomic (all the switches, except slide release, can easily be pressed with one hand)
-Accurate, at least for a pistol
-Did I mention it looks awesome?
-Rail mount for lasers, lights, etc.
-Can be a gas hog if you fire it really fast. But ONLY if you fire it really fast, otherwise it's very efficient.
-Green gas or propane only, no CO2.
