I follow HBH K frames and find that a great deal of HBH MP targets also have magnas. Doesn't prove anything but I do find it interesting. The lack of serial numbers on the back makes it harder to know if they are original.
It's in my head a bit that shooters that wanted the newer hammer also were interested in the newer magna grip.
