Well curiosity and boredom got the best of me this afternoon. I tore the trigger and hammer out and polished everything up (that little pin proved to be a pain in the ass), then gave the sear about 5 good rubs on my whetstone, lubed the hell out of everything and put it back together.
Much nicer trigger now, still stiffer than I want it to be but I don't dare do any more for fear of the hammer not locking back. It doesn't feel like an actual struggle to get it to break now though, pulls more like my favorite .22.
I am anxious to get back out and finish sighting it, but I think I am going to buy a box of UMC 55 grain to do it so I can take the russian ammo out of the equation as well. I feel like this gun has lots of potential, we just have to get used to each other.
