As a follow up... I replaced the hammer spring and lightly stoned the burrs off the trigger. I did not get the Happy Trigger since I wanted to see what improvement the spring would make first. The hammer spring definitely made a big difference. Midway was sold out so I ordered from Brownell's. The trigger breaks right at 3 lbs now and it does cycle smoother too. I haven't taken it to the range yet, but it appears the spring was a nice (and cheap) upgrade. Thanks for the info.
