Years ago we had a member in the club at which I shoot who was a former NBA guard (not a name anyone would recognize - sort of an end of the bench player) who was about 6' 6" and shot a British side by side of a make I no longer remember with 28 inch barrels and a very long (like 16") length of pull. I cannot imagine where he could have found it, but the gun and especially the shells drew a crowd every time he used the gun. Even with the very long stock, it was well under six pounds. I was fascinated by the gun and thought seriously about trying to find one (of more normal dimensions), but never pursued it. I ended up with a 6 pound 3 ounce Ferlib 12 gauge with 70cm barrels instead that works quite well for my "carry all day, shoot once or twice" gun, particularly with 7/8 or 1 ounce loads at about 1150 fps.

That being said, if someone were to offer to give me one today, I wouldn't turn it down.
