If it uses the same plastic release on the magazine body itself, rather than the release attached to the bottom metal then yes they are interchangeable, for example the 110/111/116 Trophy Hunters will all have interchangeable magazines provided they are all for the same caliber. However, to my knowledge, there are no high capacity magazines for that magazine system. The high capacity mags I have seen work with the release attached to the bottom metal. Due to the latch being on the plastic piece on the bottom of the mag, it makes it more complicated to design a higher capacity mag.
