In perturbative QCD, the masses of the hadrons involved in high energy reactions can usually be neglected. In this talk, I will discuss one case in which this ​may​ not ​be ​a good approximation, namely production of Kaons in electron-proton collisions at low (and not so low) beam energies. In particular, I will present a recent proposal to include hadron masses in theoretical calculations, and how these Hadron Mass Corrections can explain a large discrepancy observed in measurements performed at the HERMES and COMPASS experiments. ​I will​ also ​discuss some preliminary spectator model calculations designed, in particular, to test the range of validity of the ​approximations needed in the ​proposed ​factorization scheme
