trigger pull

Hi there I'm after options for adjusting. Or changing the trigger on this. Anyone got any info if it can be done please ? Or what swap out triggers are available

I’ve just bought a trigger pull gauge to try and set all my Tikka rifles to the same trigger pull weight. Having read a fair bit on trigger pull weights I’m just curious as to how heavy you all have your triggers set for stalking. I’ve set mine to a smidge over 2lbs.
