I am kind of conservative on this type of pistol. Assume that this will be more of a defensive/carry firearm rather than a range toy. Think I would fire a few hundred rounds and then decide. Before I fired a single round I would get a snap cap and dry fire DA for 500 reps, before cleaning or lubing the gun. Many of my defensive pistols that started with substandard trigger pulls cleaned up so good that to this day I have never touched them.
For me I would be most concerned about sights and grip before I went to work on the trigger. The stock sights are not designed for older eyes and standard grips usually are not grippy enough for me. LOK Grips are almost always my go to, and Dawson gets way too much of my paycheck.
Just my recommendations. Wish you the best with your project.
