I wouldn't say it "lightened up" the trigger on my P320 Carry. But it did seem to enhance the feel of the already smooth pull.
Got mine used, without the trigger work done for a pretty good price. Box paperwork, lock just like a new gun. The only sign of any use was some slight brass smears on the follower of one of the magazines it came with. Thinking some fool heard "recall" on the internet, and dumped what he thought was a defective pistol. His loss, my gain.
