06/73 Grip Retaining Pin ???

[sheepherder]

So the backs of the Mauser Parabellum grips are flat (except for the cutouts for the safety/magazine button etc)??? No 'rails' that fit inside the rectangular frame cutouts???

I've seen pics of some members grips that had 'popsicle sticks' glued on the backside of the grips, to fit inside the frame cutout. That might be a 'fix' as well.

I checked Numrich; they show 'cartridge counter' grips for the Mauser Parabellum but not solid grips. I know they used to have the solid grips because I commented on them in another old thread.
