Most of the double-action pistols I own have a short sear reset, though I haven't checked all of them. I think that is a pretty standard feature on semi-automatic actions; even some rifles have this. Some are shorter than others and the Glock is pretty short, but it isn't unusually short.
This "feature" is usually brought up as a response to the fact that Glocks are nominally double-action-only. But it is kind of like saying that a vegetable is cholesterol free -- it is a good thing, but it ALL vegetables are cholesterol free -- so calling it a "feature" is a bit unwarranted.
I like the Glock DAO better than any other DA or DAO action I can think of. The only thing I like better is "cocked-and-locked", and only one really modern combat pistol has that as an option that i can think of (the USP). I find Sig DA to be inferior even though they are very nice shooters.
Are you talking about DA/SA pistols or DAO? I've never seen a DAO pistol (other than the Glock, if you want to call it one) which did not require the trigger to be nearly fully released between shots. I've seen many SA/DA models that meet that criterion, but unless such firearms are either decocked or have the safety engaged (things one often wouldn't do after shooting them dry) they won't be in a condition suitable for safe holstering.
