I have a 257 Texan. I waited a year and a half to take it apart and treat the hammer system like they showed me how on my hw97, tx200. I felt dumb waiting so long. The hammer tension is no longer crap and the spread shrunk. I am looking at my new to me fx m3 and the first thing I am going to do is polish what I can on the trigger and find out how to remove and polish the hammer system. Polish is the word that is used but it is more like putting an edge on a blade. We can toss money at the latest whizzbang product, but it won't do more than 1ore2 thousand grit paper, stones compound and doing what you couldn't afford to pay someone else.
