I think for those who grew up with revolvers, the DA Semi auto was/is a natural fit. Some may make the shift, but .......
Revolvers in the DA were pretty safe. DA Semi auto comes inherently with a hammer, though you might be able to make something else like a striker assembly work its why bother as its more complex and does nothign.
What Glock touted the Striker as was safe, it is not. There have been a significant number of discharges with that type of gun such that it has a name (Glock Butt or Glock Leg)
The mechanism in a striker is more prone to goo jam up (Glock PR spin aside) so unless maintained correctly, it can fail. Much like an AR in the sand, yes you can ensure its fine, but you really need to know how much lube (very little) and to keep it clean (Glock and Gunny aside)
A hammer fired does not care.
Frankly most of my shooting with DA of revolver or semi auto is in SA mode.
If you train a lot you can avoid that trigger jerk, but its something that does take training.
As for no finger on the trigger, that is contradicted by train that teach you to squeeze the trigger for aimed shooting (as oppose to pray and spray)
So contrary to that statement, you do have to put your finger on the trigger, if you jerk you will miss and ..........
I can't begin to fathom the attraction to striker, the claim is its simpler but I don't see it simpler than a hammer fired (if you can learn to handle 78 lbs squeeze 12 lbs should not be an issue but for many it appear to be if not in reality in the head.
That said, both require practice to be any good and if you are good with one you can shoot the other even if you don't care for it.
Lack of practice is a two edge sword. People who don't have a lots of ND (and mostly strikers as they are more popular now) - maybe the good news is the people you don't want to have guns can't hit what they aim at (sadly they sometimes hit someone else)
