Hi G.Believe it or not 640 gun 2 became a barrel launcher and I am getiing a model 36 as a replacement.If you want to make the gun really pop get some Mother's Mag Polish and use it with finger pressure only.Buff it down with a soft clean cloth and them apply a Good coat of rennasaince wax.The new blued Model 36 is going to have to work OT to get into carry rotation as my confidence in New S+W revolvers is @ a all time low......Mike
