In Spain there kahr arms importer. In kahr arms shipments to Spain do. here in my country can not import key parts of the gun (barrel, frame and slide) but if I can ask springs. I contacted wolff springs and international shipments but they do not have the dual spring, only have the other spring.
I have received response of kahr arms, and they have said to me that sending does not do Spain. They have answered me to my technical doubts very rapid and attentive enough. I will continue looking for some shop that spring could send his his one for my kahr pm9
Thanks to all for your attention and if they know of some shop that international sending could do, please say it to me.
