Alrighty, this not exactly a review just a praise and somewhat of a guide for others...you could say.
Today, I bought my KJW G27 (metal slide...not barrel and slide) from JT for 100 bucks. For an extra 10, you can get the package that includes goggles, holster, and an extra extended mag which is a REALLY great deal.
Gun:
The gun istself shoots very well preformance wise. It has adjustable hop up that is very easy to get to. All you have to do is remove the slide and there is a tiny wheel on the bottom that you adjust. The gun has very nice accuracy, power, and kick for it's size. Another plus is that the gun itself is tiny and easy to manuver with, but then again any pistol is easy to manuver with. The mag is full metal and hold 16 shots. The extended mag holds 20-25 I think(correct me if I'm wrong). It has a locking slide and open ejection port. IF I WERE YOU I WOULD DEFINITLY BUY THE METAL BARREL BECAUSE THE WHOLE BARREL IS A BRIGHT ORANGE...VERY UGLY. Charging takes 3-5 seconds and lasts about 2-3 mags.
Any questions, please feel free to ask.
