I had already read over the amended section when I saw your post, Venator. One section which grabbed my attention was in section (6):
The licensee may carry, use, possess, and transport the pistol for 30 days beginning on the date of purchase or acquisition only while he or she is in possession of his or her copy of the license.
I think thissection coversthe possibility of the pistol not being entered into the MSP database during this time. My thought is that - although the text only refers to licensee carry - a CPL holder who borrows such a pistol should probably have the license copy while borrowing it. This might be treading on thin ice though.
