This letter is concerned with the study of the $K^-_{stop}A\rightarrow\pi^\pm\Sigma^\mp A'$ reaction in p-shell nuclei, i.e., $^{6,7}Li$, $^9Be$,$^{13}C$ and $^{16}O$. The $\pi^\pm\Sigma^\mp / K^-_{stop}$ emission rates arereported as a function of $A$. These rates are discussed in comparison withprevious findings. The ratio $\pi^-\Sigma^+/\pi^+\Sigma^-$ in p-shell nuclei isfound to depart largely from that on hydrogen, which provides support for largein-medium effects possibly generated by the sub-threshold $\Lambda(1405)$. Thecontinuum momentum spectra of prompt pions and free sigmas are also discussedas well as the $\pi^\pm\Sigma^\mp$ missing mass behavior and the link with thereaction mechanism. The apparatus used for the investigation is the FINUDAspectrometer operating at the DA$\Phi$NE $\phi$-factory (LNF-INFN, Italy).
