"To the person concerned if there's a functioning slide lock, yes it has a functional slide lock just like a real one. This is a very good gun for the price, the ABS plastic seems to be pretty durable, I haven't dropped it on a hard surface from a high place but I've hit it against a few things and it's held up really good so far. The grip feels nice and tight in your hand, really nice, hits really hard 250 to 300 FPS, recoil is pretty nice, seems to go buckwild on fully automatic :D fun stuff. Really smooth operation, Iron sights are really nice. Haven't used it in a game yet but from basic target shooting, it's very accurate from about 50-60 feet. The only bad thing about this gun I've found so far is that the trigger spring is EXTREMELY weak. Don't pull the trigger to much unnecessarily or else you'll need to replace it.
Heavy (con for some)
