We present simple, concrete, two-fermion models that exhibit thermodynamically stable Isotropic translationally invariant gapless superfluid states (breached-pair superfluidity). The mass ratio between the components and the momentum structure of the interaction are crucial for determining the stability of such states: Idealized, momentum-independent ("contact") interactions are insufficient.
