American shooters may be more impressed with strength than grace. There's a model 21 catalog from the 50's that describes a 21 that digested 1000 proof loads without damage. The British competitors in the test were severely damaged.

Personally, I think a 16 gauge model 21 is hard to beat for upland hunting. It's built on a true 16 gauge frame (the 20 gauge is adapted to the 16 gauge frame). They seldom break.
