Hi Miguel,I was one of them.
Thanks for the link You gave me,for the grips it's very useful indeed.
For the carbines it's different because for an italian citizen,for what I know,is forbidden to buy a rifle outside his own country by himself.
It is possible to order it through the ammo shop but the €300 I save it will be used for the import permissions. (Italian taxes and law.....what a very bad thing!)
But thanks so much anyway for the link,I'll try to contact them for a left handed-grip!
