I just happen to have a new in the box, never been fired MPX-P-9-KX (BOD=26-FEB-2017) with all the factory "goodies" but I have added some extras, as you can see in the photo below. The extras are 3-30 round mags, a Timney trigger (uninstalled, SIG SAUER / TIMNEY COMPETITION MPX UPGRADE TRIGGER), a Sig red dot (uninstalled), an installed Sig folding Arm Brace, along with a spare but used 4.5" barrel and matching handguard. So, other than those items, you can see the original box, lock, and docs, in the top image, then laid out for your review of the contents in the second image... does that help?
