Rambo, it does look like a toy. As TG stated it is polycarbonate, too, so it is pretty light. The slide and barrel are heavy, but the receiver is feather light.
Glocks have no external safety, just the 'double trigger' you can see there. As you can see... there is no hammer, either. Each shot is 'double action', but the trigger pull is also pretty light at 5.5 lbs of pressure.
