Given that these couplings break explicitly $R$ parity, the gravitino is a natural candidate for decaying dark matter in the $\\mu \\nu$SSM. In this work we carry out a complete analysis of the detection of $\\mu \\nu$SSM gravitino dark matter through $\\gamma$-ray observations. In addition to the two-body decay producing a sharp line, we include in the analysis the three-body decays producing a smooth spectral signature.
