I feel that there is something wrong with Rick's silencer on his Glock. While I know they are trying to be practical the Maglite flashlight tube they are using should have been cut down from below the switich and use the the full lenght of the tube for the body.Cut the tube below the switich, nake your muzzle/barrel thread plate, Have your gas tube run thru the tube, drilled and with steel wool for the baffle material, the have the end cap drilled for the muzzle.
