P85 trigger upgrades?

I've had my P85 since '92, but haven't shot it much lately mostly because I've moved on to other 9s with better triggers. I'd like to make the P85 a camper pistol, but before I move on to other accessories I need to start with the trigger.

Is there any real hope for the trigger? Replacement or gunsmith?

I don't know if they are still available but Wolff used to sell a set of 3 lighter mainsprings for the P-series pistols. You could choose the poundage you wanted & have a lighter trigger but it didn't really change the length of pull or smoothness of the trigger. I played with one in my P94 but decided against using it. I was worried the lighter spring might increase the likelihood of light strikes. That is about all I know of.
