Just my $0.02, but I think that Ruger should give a combination rifle/shotgun a hard look.
Market-wise:
The evergreen Savage 24 is defunct, and it's replacement (Model 42) is repugnant to most combi owners that had Model 24's.
The Chiappa Double Beaver, however, is a viable competitor that unfortunately is made by a foreign company that has some baggage in it's past (Armi Sport), and is currently priced 50% less than the Savage 42 - but is so far only made in .22LR or .22WMR & .410, and has zeroing issues with the factory fiber-optic sights.
IMO, a scope-compatible combination gun in 20ga or 12ga, combined with CF barrel's chambered for useful/small cartridges (like the .17 & .22 Hornets, the .256 Win Mag, & the .357 Rem Mag), and retailing (arguably) for about $500 (+/-) would be a winner.
