In this paper, we study projective Randers change and C-conformal change of P-reducible
metrics. Then we show that every P-reducible generalized Landsberg metric of dimension n 2 must be a
Landsberg metric. This implies that on Randers manifolds the notions of generalized Landsberg metric and
Berwald metric are equivalent.
