  In this work we compute all contributions to the muon magnetic moment
stemming from several 3-3-1 models namely, minimal 331, 331 with right handed
neutrinos, 331 with heavy neutral leptons, 331 with charged exotic leptons, 331
economical and 331 with two higgs triplets. Further, we exploit the
complementarity among current electroweak, dark matter and collider constraints
to outline the relevant parameter space of the models capable of explaining the
anomaly. Lastly, assuming that the experimental anomaly has been otherwise
resolved, we derive robust $1\sigma$ bounds using the current and projected
measurements.
