Sig CS tells me the gun is available, tells me to order through a dealer, two dealers I know cannot order the gun. Why put the gun on Sig's website if no one can buy one?
Does anyone know how to buy one?

Osage has it in stock at the moment. Get it directly from them.

Osage is where I had to go to to get mine a while ago. GREAT GUN!

My LGS had one. I held it and almost walked out with it. Felt great.
No use for it though. At least that's what I told myself so I could walk away.
