Foreign domain vs domain dot c o m /foreign keyword

I have a question. I want to sell one product in 6-7 countries.
I dont know which option is better for high conversion rate:

1) to use domain for each country
nome-del-prodotto . it
name-des-Produkts . de
nombre-del-producto . es

or
2) . c0 m domain with inner pages
product-name . c0 m /nome-del-prodotto
product-name . c0 m /name-des-Produkts
product-name . c0 m /nombre-del-producto
