Sorry Chasseur

In fact You are spot right. One can use a pumprifle (even though I never ever saw one in action) but the pumpshotgun is illegal.
You know more than a Frenchman, that's no minor achievement.

Talking about Bars : in fact Bars look like mean rifle used by happy trigger guys, not discriminative and likely to shoot whatever happens to move about.
Remington, Argo and 203 look less aggresive I think.
