Over a 1000 rounds through mine and it's been flawless. Love it.
Based on mine, I don't know why anyone would want to lighten the trigger, its very light to begin with.
I agree. My S&W Bodyguard 380 has a dreadful trigger pull. However, I have a feeling the Ruger SR9c trigger pull isn't as bad, and I don't want it to be too light anyway.
