    Hi All, I have a new Challenge HFT and want to adjust the weight of the second stage to a lighter setting. I've inserted a key in the adjustments screws, from left to right. 2nd stage, 1st stage, and don't know what the 3rd one does. Can someone shed some light. I've adjusted the second stage screw but nothing seems to happen along with playing a little with the 3rd screw again nothing seems to happen. Can someone explain what I am missing in understanding how to make adjustments?
    Thank you
    Jerry

    Looking at your picture , the left Allen key is you first stage weight and the grub screw with no Allen key behind the rocker is the second stage weight .
    Google image lg110 trigger and you’ll find your trigger block to look at .

    Ok, I'm trying to rotate this clockwise 45 degrees. Explain what the 3 screws do again. I apologize I'm not getting it compared to what the manual is saying I'm really confused

    When did they put two adjustment screws on the first stage adjustment.? And what benefits do you gain? The earlier models don't have this.

    I find it's best to remove the trigger guard to see what's happening inside when you adjust the screws. To adjust the release weight (2nd stage) there's a screw , normally with red loctite on it that angles into the trigger sear. Clockwise to lighten the trigger release.

    The 3rd screw from the left had red locktite on it. I'll have another go at it. It's frustrating that the manual doesn't mention this screw and what it does. The manual says the first screw on the left is the second stage. ??

    You can only see the trigger release screw if the guard is off as it's internal. All the screws that can be accessed with the guard on are for weight and length of pull really.

    Took the gun apart and sure enough there is a screw for second stage sear engagement. That did the trick. Too bad the manual doesn't mention this. along with the middle screw.(3rd from the left) Still don't know what that does

    Reason the sear engagement screw isn’t mentioned is because it’s factory set with a safety tolerance. That’s why there’s some red loctite on it.
    I’ve seen them being adjusted incorrectly only to fail and go off unintentionally, especially in the cold and also set so that the sear doesnt engage consistently, leaving the user unable to cock the gun.

    Clear instructions for the 3 adjustment screws are in the manual.

    What is the second screw in the trigger blade carrier plate for? The one directly in front of the blade? Is it a trigger stop?

    I believe it’s first stage travel

    Alex, that's my lingering question also. The manual doesn't even show the #3 screw(from the left in my picture) in the manual or in description. In my picture you can see 4 screws but only 3 are mentioned
