Many post on gun reviews and general discussions talk about a great trigger, an adjustable trigger, a horrible trigger, etc.

How does one judge a trigger?

Is there an easy way to measure break?

What exactly is trigger creep?

How important is all of this in hunting vs bench shooting?

I know it's several questions but I would like to know more on this subject. I tried searching the subject but it was difficult to pick through the clutter.

Thanks,
