The GP mag is a CZ75 mag with the mag catch slot on the front of the mag, instead of the side corner. You can take a CZ mag, drill a small hole and then make it a square hole with a needle file.
I have lots of GP mags, so don't need to do that.
But I notice that the GP mags also have the usual slot in the usual place. Sure enough, they work perfectly in a CZ.
If you have both pistols, you now have a bigger supply of CZ mags, if you need them.
