Magazine catch on Witness is about the same as all my other guns.
So what is different between the Witness and the Grand Power, the physical location of the magazine catch? If the Grand Power puts it in the front of the magazine, where does the Witness put it, and what is different between the two?

Someone else will have to chime in on those answers.  I only know that the two witness guns I have are very much like the stiffness of all my other pistols.  Glock, Ruger 1911, Para 1911, Sig P229, High Power...They all feel about the same.

I finally got to the range with my p40 after getting it back from Colorado Gun Works about a month ago. After moving I was a bit lazy about getting the gun stuff unpacked. The mag release seemed a very stiff
at first but seemed to loosen up a bit with use. I put 6 mags through it (3 mags twice each). The mags did not drop out! However, when I sent it in, I told them that the gun would consistently misfeed the last
round in the mag. The said they "could not duplicate" the issue. On all 6 mags the last round failed to feed. Oh well.

How many rounds are you loading? I have not had that problem. I typically load 13 however.

It doesn't matter how many rounds. 4 or 14 it always misfeeds the last round.

Most likely attributable to a rough breach face.  The case head is having trouble sliding up the face as it feeds, without a round beneath it to help.

If you polish the breach face, the last round feeding problem should go away.

Got my P40 out to the range today. 200 rounds through it. 2 failure to feeds towards the end of the session. The gun was rather dirty , not sure if that was the reason or I limp wristed it. Other than that, it ran excellent. All the ammo I shot was 1200 + fps. 180 grainers.

Great to hear 10Tens.  The Grand Power sure is a sweet shooter.

I'm amazed at the accuracy of this pistol right out of the box. 2 inch groups all day off hand with no bench rest at 30 feet.

Any more reports pro or con on the mag drop issue, and how it is being dealt with?

I don't think I mentioned it above, but getting the service done and the turn around time was excellent. About 3 weeks door to door.

Only issue I have is with one of my 4 mags . It fails to lock the slide open on last round.
