The updated hybrid model is applied to $p+p\to Λ+X$ and successfully reproduces the detailed kinematic dependence shown by the data. The hybrid model is extended to include pion beams and polarized $Λ_c$'s. The resulting polarization is found to be in fair agreement with recent experiments. Predictions for the polarization dependence on $x_F$ and $p_T$ is given.Talk presented at Hyperon99. Latex2e and 4 PostScript figures.
