Ok everyone, I took the sideplate off and cleaned thoroughly, and re-lubed with clp. Still way too light trigger pull. I do not have a trigger pull gauge, but I estimate it is about 2/3 as light as my 640 pro J frame.

I took back to range and still getting several light primer strikes with 38 ammo. Winchester white box and also federal ammo.

Strain screw is adjusted all the way in.

Are longer strain screws available ? Or should it go back to the
Factory ?
