Actually Glock safe action (striker fired) pistols first trigger pull is more like the DA pull of a DA/SA pistol, only better than most. The subsequent trigger pulls if you only release the trigger to reset, is more like a SA pistol, still better than most DA/SA pistols in SA.
This is a perfect example of how YMMV often applies to your experience with other triggers. I don't doubt the sincerity of your position. I would have when I was more naive, because I was under the mistaken belief that all people shared similar firearms experience.
This is especially fresh in my mind as I just spent the weekend with a Championship level Glock shooter and we discussed the different techniques needed between different striker fired pistols as opposed to DA/SA pistols. My recent experience left me with the impression that:
1. The Glock Safe Action trigger, I just can't bring myself, given it's history, to call it a DA, has a trigger stroke similar to a serviceable revolver trigger. The SIG DAK, Para-Ord LDA or Kahr triggers have trigger closer to a tuned revolver action.
2. When release only to reset, the Glock does away with the light takeup, but keeps it's hard/spongy final press. This is nothing like any factory SA I have felt, with the possible exception of the H&K USP and P2000 family, on a DA/SA pistol...mostly because they lack the travel needed with the Glock trigger.
3. The trigger of the S&W M&P or Springfield Armory XD/XDm can be tuned closer to a good SA trigger on a hammer fired pistol
