We report the critical current density J_c in K_xFe_2-ySe_2-zS_z crystals. The J_c can be enhanced significantly with optimal S doping (z=0.99). For K_0.70(7)Fe_1.55(7)Se_1.01(2)S_0.99(2), the weak fishtail effect is found for H II c. The normalized vortex pinning forces follow the scaling law with a maximum position at 0.41 of the reduced magnetic field. These results demonstrate that the small size normal point defects dominate the vortex pinning mechanism.
