Things I liked:This gun is very well made. It is mostly metal besides the grips. The blowback is also very nice and the gun actually gives you a lot of shots with just one CO2 Tank. Things I would have changed:The magazine is a little depressing. Although it holds 15 shots, it is made out of plastic. Also, you have to hold the spring down to load the gun because there is no lock to hold it down for you. It also doesn't even drop out of the magazine, you have to manually push it out. What others should know:When you first take the gun out of the box, the slide, the hammer, the trigger, and the safety may seem a little "rusty" so you may want to buy some oil and spread it on the slide and the other components.
