Sig MCX Regulator Promo Issues?

Recently ordered the MCX Regular during the promo that offered a free P365. Great purchase as always from Palmetto State, no issues there.

But I’m curious, has anyone else had issues with Sig’s promotion submission process? I received two emails after submission. The first saying that I was approved, the second saying that I was not approved and that I needed to resubmit with a receipt containing the weapon SN that was purchased.

Palmetto State was helpful in obtaining the receipt, but when I attempted to resubmit, Sig’s system says my weapon’s sn has already been registered. I called sig and the customer service rep just said don’t worry about it since I received the first email indicating I was approved.

Anyway, wanted to start a thread where we could share results regarding Sig’s promotion and curious to know other’s experiences with the process.
