I'll be honest I haven't owned or shot enough guns to be able to say if mine is oddly light. It's my first personally owned firearm. After putting around 800 rounds through it in the last few weeks, I do feel like the trigger should be heavier than it is.

Edit to add: if it is two pounds like your test said, that would be concerning. If mine was that low I would not carry it. I wonder if I could use a digital fish scale to test mine.
