chasseur,

I think I see your point... my 28" field-grade Ithica/SKB is indeed heavier on the scale than my dad's benelli montefeltro, but the o/u SKBs are not known for being particularly light and the montefeltro is THE lightest autoloader in the world IIRC. both are 20ga.

my double sports fixed-choke 28" barrels, his is 26" with choke tubes, about an inch of overall length difference...
