Because of the way it is boxed, there is no indication that a mag is missing, if you have gotten used to getting just one (anyone think "Kimber"?).
I was already suspicious of some of these rock-bottom prices at the LGS, sounds like they sold less for the lesser price. As I mentioned before, the GM guy said mine came in overnight. He had me check for the parts (allen wrench for sight adjustment, mags, lock) before they did the paperwork. He knew what he expected to deliver. At what I paid, I should have gotten all the parts.
