I want to give an update. I measured the SA trigger pull at 7.5lb. The DA was more than could be measured with the digital gauge. The inside of the gun was very clean. All looked fine until I took it apart and looked at the engaging areas. Lots of burrs and unevenness. Since I've only done one other trigger job, I was probably too easy on the stone. Replaced the rebound with a 14 lb spring like H Richard suggested. SA trigger pull is now just under 3 lb and DA is just over 9 lb. It is still not butter smooth but probably as good as I can do. Thanks for everybody's help. I'll be back with more questions shortly.
