Use of hammer and firing pin instead of striker system

Anybody know where a comparison list of the lock times for various pistols can be found on the web?

I seriously doubt that such a thing exists. Most APs (if you want to include them) have a very similar striker design, so there is not a lot of variance.

If I had to guess, I would say a Morini with a titanium striker is probably it. Or not.

He also tried different mechanisms, designed for rapid fire competition, also with hammer, as far as I remember, to get a faster percussion.

Someone in our club has a Patro, it rarely works and has to be retuned with every change of ammo

Palamà is still working, as a gunsmith. Many say he is the best gunsmith in Italy. I would write an email, about these malfunctions, roberto@robertopalama.com

Back in the mid 80's Morini had the model 102 which was a electronic triggered sport .22, it used a striker/spring in the slide released by a solenoid from below.
The biggest problem with this pistol was the balance of slide springs vs. striker spring.
With the striker compressed the rear of the spring pushes against the back of the slide, once released the striker flies forward to fire the shot but the spring reaction pushes the slide backwards, sometimes far enough to slightly open the slide and cause a light strike or malfunction.
The fix was to either increase the slide spring tension which could also cause a feed malfunction, or increase the mass of the slide which affected the pistol handling.
When working well it was a pleasure to shoot, but very hard to keep the balance happy and the pistol is now part of history.
