I hope to undertake a similar course of work to my own 38 and it can only get better. After initially struggling with the 38 (I'm chopping and changing guns too much of late) I got it working right for me and as you say accuracy is very good. Its as dry as you like inside unfortunately and as such I don't want to use it too much before correctly lubing it.
Would be good to hear some feedback of how you get along post tweaking work?
