  We analyze $K \to \pi\pi\gamma$ decays in the framework of Chiral
Perturbation Theory. We study the different Dalitz plot distributions, trying
to find regions where o($p^6$) contributions could be more easily detected. To
fulfill this program we compute all the the o($p^4$) loop and counterterm
contributions, finding a substantial agreement with the existing calculations
and adding some small missing terms in $K_S \to \pi\pi\gamma$.
