Thanks for the kind offer, Jim. I do appreciate.
I have taken a look at the site you pointed me too, and they advertise $500 in fees to start, and then additional charges between $200 and over $1.000.
Which means that if I bought a $250 gun, the total I'd have to pay (price + fess & charges) would be at least $1.000.
Moreover, they require an import certificate which is never delivered by any French authority, as buying a black powder replica is free in france when you're over 18.
So now, I know I won't ever be able to buy a gun from any American dealer, and I understand why no dealer wants to take the hassle.
Once again, sincerest thanks, Jim. Should a miracle happen, I would take up tour offer gladly, but miracles don't happen too often in my neck of the woods...
