Best way to get a shotgun with one-two punch?

[waxen flare]

Is there an area to farm a shotgun that might have that roll or is there a craftable one?

[rain geyser]

wq campaign should give you a Ragnhild-d pretty early one, craftable kinetic slot

wastelander from dares can be crafted, same slot

I don't see a current craftable one available in the energy slot, but the neomuna/terminal overload, dead weight from gambit, and last man standing from the season can roll with it
