Accutrigger pull weight?

Hi all, I have a model 11 FCNS and a model 10 Predator max-1. I have both accutriggers adjusted to the lowest pull weight. The model 11 consistently breaks at 2.25 lbs., the model 10 consistently 1.5 lbs.. Is the trigger return spring the only difference in these triggers?
Thank you.

I think they have different accutrigger models. A had to make a spring to get mine to break at 2#s

There are two different Accu-trigger springs: standard and varmint/target which at low setting give around 2.5 and 1.5 lbs, respectfully.

Thank you for the replies.
