Obviously the PSP mags won't fit the M8 since that they don't have the relief for the side magazine catch. However, the PSP had the heel mag release and both the M8 and PSP mags look very similar. I am thinking that M8 mags can be used in PSP...can any HK P7 expert verify?

They are not.

Nope....

Will not fit.

P-7 M-8's have a lug at the top for the magazine catch.

Oh well...c'est la vie.
