Ive owned two short 10s over the years. 1 was a T. Woodward that weighed under 8 lbs....it was built as a game gun, most people would have to look at the barrel flats to know that it was a 10.
#2 was a W&C Scott built on the Baker/Scott action (Crystal cocking indicators), that one was definitely a 10 gauge. It looked it & felt it. I think it was around 9 lbs, and the barrels were as thick as an artillery piece.

They were expensive to shoot (I didnt load for them). Neat to own. Didnt really fill a niche or tug at my heart strings all that much.
