I took them both apart, and can confirm my m17 does have a slot for the safety, the "m18" with the m17 does not, although, the non MS one does say m17-xxx on it and the MS one says m17xxx on it. The box for the m17 has MS at the end of the model number, and the "m18" has the same model number but no "MS" at the end of it, all serials match the box too.Chiming in here with what might be helpful information: Sig also produced and sold a "P320-M17" and "P320-M18" that had the style and appearance (as well as sight mounts and even box of the M17/M18) but lacked the manual safety of the true m17/m18. This confused and annoyed me greatly back when I was looking for an m17 and needed the safety for a project. To tell if you truly have the M18, of a non-manual-safety cousin its FCU is very slightly different than the p320.

As you can see above, the military model FCU has a vertical cut instead of a hole on the rear right side of the FCU, this is to allow for the manual safety. This will help you determine if you have a true M18 or the non-manual-safety version. As you can see, if it's the version without the manual safety, you may not be able to add one yourself unless you cut a channel in the FCU.
I sympathize with your situation because I was in the same one but luckily noticed when inspecting at the Cabelas and was able to cancel the transaction before it was too late.
Sorry for the junky pics. Hope this helps and best of luck!
