I guess I'm from a different school of thought here. My CCW's - and home defenders - are not resprung nor do they have their triggers polished. I do deep clean them pre and post break-in - and break them in, either by dry-firing or shooting them, or some combination, to about 1,000 rounds equivalent. This preserves the stronger hammer spring's ability to pop any & all primers - and I can say, in court, if need be, that my CCW's aren't altered. They aren't plinkers! This started with my 296, then my 2" 10 & 642, and, finally, my 4" 64. The 642 is quite serviceable - but the K & L frames are even better (As said, better geometry!). Learn to adapt to your revolver - it's far more reliable that way.
