I'd buy an SX3 camo with the 26" bbl and either use a rail on the action with reflex for turkey and remove for wing shooting or I'd buy the 26" model and buy the 24" turkey bbl that has the cantilever mount. You'd be a simple bbl swap away from wing shooting and the reflex would stay zeroed due to the CL mount.

That said, the SX3 is not the lightest 20, so you may want to look at the Benelli if you want to go light.
