Walt J Kuleck's test (which is included in the second of his books, as you listed them) included testing with:
- A standard GI firing pin, in steel
- A thinner, 9mm firing pin, in steel
- A GI-thickness firing pin, in titanium
- A 9mm-tyle firing pin in titanium
All tests were carried out with the same pistol. They started out with a slide drilled for a 9mm firing pin, and bored it out to GI-spec diameter to test it with the thicker firing pin. Predictably, the lighter 9mm firing pin was an improvement over the GI part, but the titanium firing pins made the biggest difference of all.
On the other hand, some don't like titanium firing pins, because when combined with the light mainsprings that some 'smiths prefer, they can induce light strikes.
Too many people miss the silver lining because they're expecting gold.
