It makes perfect sense that a gun with 28" barrels will handle differently than an identical gun except with 30" barrels. Likewise, they will have different weight and different balance point.

Remember that swing effort is measured as moment of inertia. MOI is the resultant of weight and radius from some pivot point with said radius squared. That said, the extra two inches of barrel length are in the place where they have maximum affect on MOI. Discernible difference among similar guns with differing barrel length should come as no surprise.

I expect that the Brit trade, as a nod to standardization, made 28" barrels when possible. If you didn't stand your ground on desired barrel length you got 28". Fashion was more interested in the name on the gun.
