As you can see, I went back to my previous message to show the K2P and Witness with the MG WIT 9-SF mag in it.
To reiterate, I was sold the MG WIT 9-SF as the OEM mag for the K2P even though the labeling is clearly for the Witness. And that isn't to say that it isn't the exact same dimension as what the SAR mag would be, and to match the SAR mag, the baseplate was swapped for a metal one. However, as you can see, the length of the mag or how it sits in the pistol is different in both the Witness and in the SAR.
Rather than showing the mags in the gun, I just took pictures with the mags out of the gun and had quite the discovery I hope I can get help with.

In this picture you can see the mags are similar other than the holes are on the right side of the MG mag and numbered to 17. When they are flipped over, you see the SAR marked to 15, the Witness unmarked, but clearly the same as the SAR mag, and you will see the stamped MG WIT 9-SF. Clearly MG=MecGar WIT=Witness 9-SF=9mm Small Frame

Now is where it gets weird..when spinning them around I noticed the front of the mags was different, a lot different....

A hole in the face of the mag the others didn't have and instead of a straight cut on the top, it has the "pointed" from edge in the metal I hope you can see in the black on black photo.
Is this a "new" version of the mag, and is it fully backwards compatible? What is the hole for, some new feature?
Should there be any feeding problems with the Witness or SAR?
Thanks
Now, where it gets weird, at least for me, is the next picture
