How exactly do I copy/paste weight paints on a select bunch of bones/mesh on one model to another model?

The models have identical meshes and identical armatures on the hands (where I am trying to transfer weights between)
My goal being to just copy/paste the weights from Model 1's hands to Model 2's hands as they are the same and it'd save me a lot of hassle having to manually weight paint the second model's fingers

Right now all I've done is brought in both models to the same blender project but unsure how to transfer weights
