The "outside" testing done by Sig in Germany is a European requirement and not something Sig DE does out of the kindness of their heart. My last two Sig's; one manufactured in 2012 and one in 2013, had most certainly been test fired so I'm not sure where you are getting that idea. As for the MIM shop thing how could you possibly know that? I have been to the Exeter plant and they certainly do not give away any trade secrets and only allow very limited areas to tour as they are very protective of their processes.
