Disassemble the triggers. Put all the pins & screws back in. Heat it where it needs t be bent & slightly bend it. Take it back to the stock & fit it. This may take 1 time or a dozen times, do it til it fits Correctly & you don't have to
pull anything to make it go in.....
If the trigger is already inlet & you bend it more, the inlet will be too long & you have some fill work to do. If it is straightened out, then it will be too long for the inlet. On all of the rifles I build, I shorten the triggerplate 1/8" on each end, just in case I have an issue when I get to this point. If it is a total washoutscrewup...... I can go to a new trigger inlet & not be over inlet.
Lots of times you have to bend them a tad in the middle & then straighten them a tad on each end. I bend them where they need to be to conform to the stock properly & then go on. But I get it all shaped Before I inlet it, so I don't have to fill a inletting error.
Usually you can bend the ends pretty easy a tad without heat, but the middle is different. Don't pull or stress the middle at all trying to bend the ends or you will mess it up. And if you don't have the screws & pins in, that is a weak spot & they will bend there & mess the triggerplate up & you get to buy a new one....
