Narrative:

Tower issued a wind shear alert for runway 28 as we approached the final approach fix. We advised tower we were going around and started to climb to the missed approach altitude of 4;000 ft while continuing on the localizer. As we were approaching 3;000 ft; tower told us to maintain 3;000 ft and turn right to a heading. We overshot to around 3;100 ft before we could stop the climb.
