The form factors of B-1 --> pi and D-1 --> pi transitions, where B-1(D-1) is the 1(+) P-wave <(Q)over bar gamma(nu)gamma(5)q> meson state, are calculated in the framework of the light cone QCD. Furthermore, these form factors are compared with the pole dominance model prediction using the values of the strong coupling constants g(B1B*pi) and g(D1D*pi), and a good agreement between these two different descriptions is observed.
