I bought the standard fire control group kit with the lighter spring kit and they advertised 4.5 pound with polishing.
The problem is: you fire the round and everything appears great, but the trigger is locked and you have to nudge it forward to fire again. Is the spring to weak to cause it to return to the correct firing position? I ordered the stock spring set, to see if it was the problem. Installing my other lowers and it works fine. Maybe a lemon? or something the light spring is not causing the hammer to release to correct firing position.
