Hello Mauro,
I do not have an answer to your question,...sorry.
I have sent to your private e-mail address the contact info for "Guisan". Thought you might want to make his acquaintance since he is a fellow European...
Let us know if you find out if these muzzle protectors were made for 9 mm. barrels or not...
Regards,
Pete... <img border="0" alt="[typing]" title="" src="graemlins/yltype.gif" />
