It doesn't surprise me that MB can't get good contact with Sig. I've had some disappointing interactions with them myself.
Don't get me wrong...I have two Sigs and I love them both, but....
I warranty registered both Sigs in Auguest- they send you some kind of little knife for doing so (you can never have enough crappy little knives!). Still waiting.
I also bought a GSR in August and got a $100 certificate for Sig gear. I still haven't recieved all of that. It dribbles in one hat, one shirt- whatever, at a time.
I sent them an email to politely complain, my point being that I know they're not in the trinket or clothing business, and I would have bought the guns anyway, but for doing so THEY gave me the free stuff, so they should be johnny-on-the-spot about delivering. If you're doing a promotion why wouldn't you have the stuff and build the goodwill by giving people what you say you'll give them?
Anyway, the stuff isn't that important...I can wear a hat that says S&W or CZ or whatever and they don't seem to care.. They just seem to be in their own little world up there in NH.(Sig Sauer, that is...you NH'ers are fine folk)
