We show that the processes ..pi../sup +/..--> gamma..e/sup +/..nu.. and K/sup +/..--> gamma..e/sup +/..nu.. with hard photons can be calculated accurately and without free parameters in the quark model. We extend the calculation to gluon radiative decays P..-->..Gqq-bar and P..-->..GX(hadron) of heavy pseudoscalar mesons and show that while for former is too weak to explain existing data, the latter could be the dominant hadronic decay mode. We test our approach by studying the inclusive decay properties of the heavy mesons.
