If you’ve got a break-barrel that matches your fixed barrel rifle(s) is there any reason to keep the fixed barrels? Given a late middle age, it’s unlikely I’ll physically wear out a break-barrel. There are lighter for the aging frame to heft, and are less complex to strip and maintain, an important feature as the clock runs down.

I don’t really like break barrels as much as direct-loading fixed barrel guns simply because of some additional and possibly theoretical rigidity. They’re heavier so maybe that makes them easier to keep on aim but then they’re heavier so muscle tremors kick in earlier.
