I know that fluted pins were standard on all Mauser and Kreighoff Lugers but I don't know about Simsons, perhaps Ed will fill us in.

Norm,
I was unaware that steel case German Army ammo was introduced in WWI.
Also, at least for Mauser's war production Lugers, flutes were designed to clear debris not to vent the breach block area.
