  Models of extended gauge mediation, in which large A-terms arise through
direct messenger-MSSM superpotential couplings, are well-motivated by the
discovery of the 125 GeV Higgs. However, since these models are not necessarily
MFV, the flavor constraints could be stringent. In this paper, we perform the
first detailed and quantitative study of the flavor violation in these models.
To facilitate our study, we introduce a new tool called FormFlavor for
computing precision flavor observables in the general MSSM. We validate
FormFlavor and our qualitative understanding of the flavor violation in these
models by comparing against analytical expressions. Despite being non-MFV, we
show that these models are protected against the strongest constraints by a
special flavor texture, which we dub chiral flavor violation ($\chi$FV). This
results in only mild bounds from current experiments, and exciting prospects
for experiments in the near future.
