Dig's theory makes sense if it is feasible to ship the gun for speicalist repairs.
Current EU and national laws stop this. Either by design or accident they have turned high end shotguns into liabilities rather than assets.
The antidote is simple: bolted stocks, monobloc parrels, coil spring actions. In short, a locally, often owner serviced SXS.
And that means that a Beretta 626 outguns most other SXSs. The cost of one used is low enough to get it to sensible bespoke level and no specialist work is needed for that.
