Can I shorten a Witness K10 mag?

[NewShooter]

I ran a snap cap through my steel compact witness with both a K10 mag and then the standard mags. The barrel was removed. I noticed that the K10 mags fed the rounds up, and they never jammed inside. The standard mags fed the rounds down. Would it be possible to shorten the K10 mag for use so that it fits flush in the magwell?

Have you taken any measurements of both feed lips?
