You are not alone.I have the same issue with the Crown trigger sticking on a rifle that was just days old. Other than polishing the trigger wheel as suggested which requires taking the trigger out of the gun, trial and error and a lot of patience is what it takes. Both the first stage travel and second stage work in unison with each other. if you adjust one, you will need to adjust the other. I found that the best remedy is turning in the second stage screw a hair at a time as well as the first stage. at some point, you will reach a point where the sticking is eliminated. However, the down side to this is that in most cases, the trigger pull weight is increased.So do you want a little heavier second stage or a sticking trigger? Myself personally I want the light trigger.In order to get this on my Crown, I have the trigger weight down to 10 ozs, but I have a "stick / stop" at the second stage which is quite definitive but good, as I know at that point, the next slightest pressure on the trigger it will fire. Not the way it should work, but works for me. Also, I have noticed that if you cock the gun and hold the lever back just a tad, the trigger will un-stick { if that is a word } don't know why. So just drink a few beers, calm your nerves and have at it! One other point, I have found out that while it is easier to adjust the trigger while the gun is out of the stock, you CAN if you wish, adjust then trigger without removing it from the stock. and risk losing the minute ball bearings and springs in the hammer spring knob.The second stage screw is pretty accessible thru the trigger guard. The first stage is harder ,and takes an allen wrench that the " L" portion has been shortened to allow access. Don't try this method if you do not have the patience
Good Luck
