Well, the original poster did not specify what the gun is for...Competition, carry or just target practice...
If you're carrying then leave the trigger alone. It's set up just fine from the factory.
If competing then send it off and get the whole chalupa!! Spend 200 bucks and get the pretravel, overtravel, reset and trigger pull done...
But I'm very confident in what my 20 minutes of tinkering got me. Trigger is a lot smoother and lighter, but I do shoot USPSA Production division with it. So, it's perfect for what I'm using it for. It's not a carry gun, it's not a service weapon....
