Its not just a question of total travel though. The M&P trigger take up has basically no resistance, you can push it right to the wall and know when it is about to break. The intial take up on the early M&P's was gritty and they were generally crappy triggers but I got used to them.Having owned several M&Ps, Glocks, and Daggers, I was intrigued by your 'long trigger' comment. I got my most recent Dagger out of the safe and used digital calipers to measure trigger travel from fully forward to striker release; the result was 0.3" for four separate measurements. Since I no longer have any M&Ps, I wanted something more than fading impressions from my memory to reflect M&P trigger travel. I found the illustration below on the M&P Forum that shows a Gen1 M&P with a trigger travel of 0.3" from fully forward to striker release.

The glocks i have shot I would describe as having a trigger like rubber band. Tension increases all the way until the trigger breaks. Having spent very little time behind one, I have a hard time judging the break and I don't care for that style take up, especially not if they have any over travel.
I'm not saying one is better than the other, both can be done well or poorly. The Kahr K9 I have is buttery smooth and breaks very clean, it is easily argued to be a better trigger than my Gen 1 M&P, but I shoot the M&P better. I also carry a 2.0 and have a shield. The dagger is probably as good or better quality as any of them but it doesn't sound like the trigger will be consistent with what I am used to.
