My 16ga is a little heavy, it has 29" barrels, POW stock and semi beaver forend, its just over 7 lbs.
I could see an english stock and splinter forend coming in close to a pound lighter.
My 28ga is right at 6lbs.
Mine are Zeus models, the Venus model is supposed to be lighter.
I know someone that ordered a 16ga Zeus, he got them to weigh the stock blanks he had to choose from, and he picked the lightest one.
His gun is set up like mine and his comes in right at 6 lbs.
I believe the Venus model in the 28 gauge is on a smaller frame as that's what my guide friend ordered. I think the weight is supposed to be around 5.5 lbs in 28 gauge. She ordered the Venus because she wanted a lighter model to carry.
