Well, my gun was took one day to get here and that's really fast! Over all the gun is great good distance, Can be fixed really easy if you know how to fix an airsoft gun. The gun comes apart so you can fix the insides, and that helps a lot! The hammer works also. At first it may be hard to cock back the slide but it gets easy over time. Now with the safety.It has two safety's ,One is located in the back of the gun. You must grip the gun firmly in order to pull the trigger all the way back to shoot. The other is right next to it. Now most people see it in the manuel that comes with the gun but because its engraved in plastic they think it does not work. That's wrong. It does work fine. To put safety on you must push the button up. It may be hard at first but you'll get us to it. Once the safety is on you can't cock the slide back, and the hammer will not let down you try to push it down. Now if you cock the hammer back and then put the safety on, even if you grip the other safety and pull the trigger it wont work. The sights on this gun works good. Now if you want to change the hop up you can't they already fix it so that it's in it's right spot. The magazine has some pounds on it and that's good. It's just like the real gun it's self. So if your worried and don't know if you should buy it, buy it!
