The two most common issues I've seen with French guns are pitted bores and heavy triggers. Not that you won't find French guns with good bores and very nice triggers, but having looked at a bunch of them over the last 35+ years, I'd say both of those are more common with French guns than with doubles from any other country that produced a significant volume of guns. On the other hand, it's very unusual to find a French gun that isn't well-made. Certainly more common to find "crappers" from Belgium and Spain.

Rocketman, the problem with evaluating French guns made for export is that not very many fall into that category. Manufrance was the real volume maker of French doubles, and they never made a very concerted effort to penetrate the American market. The French were well behind the British, Germans, Belgians, Italians and Spanish in that area.
