A He-gas compressor system is used to determine the dependence of the Curie temperature ${T}_{C}$ of polycrystalline GdAgMg, EuAgMg, and EuAuMg and the N\'eel temperature ${T}_{N}$ of GdAuMg on hydrostatic pressure to 0.8 GPa. The $\ensuremath{\partial}{T}_{C,N}/\ensuremath{\partial}P$ dependences found differ significantly from those estimated from earlier thermal expansion studies on the same samples. Only for GdAgMg does the magnetic ordering temperature decrease with pressure.
