A simple and efficient method for generating gap solitons in a spin-orbit-coupled spin-1 Bose-Einstein condensate is proposed, where two moving solitons can be generated by free expansion along the spin-orbit coupling dimension, identified from a generalized massive Thirring model. The dynamics of the gap solitons can be controlled by adjusting spin-orbit coupling parameters.
