Considering it is a pocket gun, they did design it with a long pull. But I understand some came out of the factory with overkill in that department.
I've probably put over 500 rounds through mine at this point, and I'm satisfied with the trigger now. If it's really a problem, I'd take it to a gunsmith and have them to a trigger job on it. They should be able to smooth it out.
I wouldn't recommend any lighter springs. For a carry piece, I want something with a long, heavy trigger. In a critical situation, I'll have enough adrenalin pumping through my veins to make 8 pounds feel like 8 ounces.
