Yep, call Sig. They are a great company to deal with. For Christmas of 2009 my wife bought me a 4-Star 120 from a buddy in our club, he had bought it directly from Sig. While I opened the box to pull the instructions to read through, I didn't take anything else out of the box. A couple weeks ago I was getting ready to start getting it prepped to build and I opened up the box to start looking over the plans. Nowhere to be found in the box. Called Sig the next day and I was full prepared to pay for a copy of the plans. I told her what had happened and she asked for my address and politely said, they will be in the mail tomorrow. No charge!!!
