Old, if the Blackhawk stock you looked at was lighter than your factory stock it was probably the non recoil stock like this:

A Remington Blackhawk recoil reducing stock weighs 1.15 lbs and the forend weighs 7.4 oz. I would think that's more than your factory stock. How much does your wood(?) stock weigh? But, you may have one of them loooong woodies
