Can I lighten my 11 accutrigger?

Is there any homebrewed way to make the model 11 accutrigger, which they claim goes down to 2.5 lbs or something like that, a little lighter? I am not familiar with the accutrigger really, never had one apart, but would like to do some work on my new one to try and "improve it". You know, if it ain't broke, fix it till it is.

You can get the light weight spring used in a model 12. SSS is the onlt place I know that sells them.

Does this just replace the large spring in the rear of the trigger that you screw in or out to adjust the pull weight?

Yup
