Hi, i have problem with my ksc 18c glock, its something with the gas, i don't even can't shoot all clip of ammo, becouse the gas is out allready. It's not all, when you turn the gun 180 deggres (shoting like a gangster

) the gas sprends on your hand. I think it too much gas given, so i have to somehow decrese it. Please help me, i don't whant to broke my pistol!
