TX200 trigger adjusting.

[Riffler]

I'd like to lighten my trigger, can you lighten the trigger pull, using the most rearward screw without this affecting the first stage and second stage settings?

That is correct but, adjust in 1/4 turns and don't go too light, not only for trigger safety but, doing so can also stop the mechanism from correctly engaging.

[Riffler]

Thanks.

Can you test fire the rifle without the guard being attached (saftey issues aside) or does the rear trigger guard bolt have to be in position?

[Sake-san]

No need to have the trigger guard on, but you can also just remove the trigger unit and the piston, just use the piston latch rod to cock the trigger mechanism. Easier and ultimately quicker than cocking and firing the gun.

It might also be worth giving the rubber butpad a gentle clout with a mallet after adjustments, just to check the triggers knockproof.

This sounds like a good way to go, but will this not give the wrong pull weight, as the piston latch isn't holding back the spring compression?

It works fine for me, you may indeed need to a little fine tuning after but, still easier than doing it all assembled.

Well, we tried the adjustments as suggested here, but couldn't get a 2nd stage, just an unpredictable release (no stop) at the end of 1st stage travel, despite all 2nd stage additions being one eighth turns
Worked on the trigger in and out of the action.
My mate had a good way of trigger testing with the guard off, which is to use a couple of plastic cable ties holding the action to the stock instead of having to refit the trigger guard for cocking. This worked well.
At this point I left him with the gun, thinking it would need to go to a gunsmith to fix, then i got this email

"Wound out the first screw half a turn, and wound in the second screw a quarter of a turn . . . . and . . . .
. . . it works again !! Nice clean stop at the end of stage one . . . and a great shot release!"

I'll collect from him soon and see how it is.

For those that read this and don't know. Adjust the weight of pull a fraction heavier than what you want. When the trigger guards rear screw is snugged up it sometimes lessens the weight of pull. I like to set my triggers with just enough weight of pull to make the trigger blade go back into the first stage if released without firing. I was adjusting for just enough weight and, when I snugged up the guard, I had the floppy first stage. Added a little weight and all was well. In my defense, it was my first try at trigger adjusting on a TX.
