There is a pin from a fabricated part that engages the hold-open and pushes it up into position independently of the magazine button. It's not quite clear how the added part is shaped...Or attached to the safety...

I know there are a couple members here who collect Martz conversions, and Martz stamped MSTR on the side of the modified Lugers. Maybe one of those could tell us how it operated??? ("junglejim" was one, I think)...

Edit: Here's the full MSTR patent file...
