Is my Arizona concealed carry permit honored in Colorado?
Permit reciprocity is decided separately from the firearms status shown on this page, so it is not answered here. LawLert publishes Colorado's recognition list, with the statute or agency page behind it, at lawlertapp.com/firearms/CO/reciprocity. Permitless carry, where a state allows it, is a different question again — it does not make an out-of-state permit valid.
