I think you would be very displeased with the pattern out of your revolver.
My Home defense is a .44 magnum S&W model 629 with Crimson Trace laser grips and a small but very bright flashlight jury rigged to the underside of the barrel. I have both good light to get a POSITIVE id of the target and the red dot to place my shot. I have been using this set up for many years and I practice with it often. Needless to say it is not loaded with bird shot!
