No, The PSP mags are different than the M8.

No the P7M8 will not function in the PSP do to the difference in mag releases on both guns.

I can say that Mark knows his P7 series of pistols. If he says it won't work it won't work.

An M8 mag won't fit into a PSP magwell. The mag catch's "tooth" sticks out and won't let it in.

You can sorta go the opposite way, as a PSP mag will go into an M8 and feed/function BUT you have to hold it up in there. Not something you would want to do, but possible in a dire emergency (that I can't imagine, but had to see anyway).
