I don't know and don't have a scale that will weight the gun. The digital scale I have at home doen't give real accurate readings below 15 lbs. Sorry
They do not feel excessivly cumbersome, heavy, or unbalanced. The gun feels perfect until the Surefire is added. The Surefire makes the weight a little more noticeable, but the gun still feels well balanced. Hope that makes sense.
