The role of gauge invariance in calculating 
radiative weak decays is clarified. It is shown that the gauge invariance,
particularly in the context of vector meson dominance, severely restricts
the contributions mediated by the usual weak non-leptonic Hamiltonian
dominated by u and c quarks with one photon attachment. We also
discussed contributions which are not restricted to vector dominance.
