My factory synthetic stocked Ruger MK-2's weigh 7 lbs unscoped. Right at 8 with scope and rings. Not a lightweight, but manageable. The wood stocked versions weigh about 1/4 lb more. Unfortunately there are very few options for a lightweight stock.
Loosing weight in a gym has nothing to do with carrying a gun and just a few ounces can make a huge difference in how a gun carries and balances.
