Things I liked:All the levers on the gun works realistically. The weight of the gun is a little heavier than what I remember the real gun felt like but I rather it feel heavier than lighter. The new NS2 gas system is amazingly proficient, the gas does not leak so I can keep the gas in the magazine for days and still have the same charge the next time I use it. Plus this gun shoots a lot harder than most guns using Green Gas. Gun is also very accurate. I've only shot at things up to 15 feet but the difference in speed and accuracy on this gun compared to my old WE 1911 is astounding. Things I would have changed:I wished the grips were customizable. The grip on this gun is made out of ABS Plastic and although does the job well, it feels uncomfortable.
