My P345 is a fine shooting iron especially in that price range but after complete dissasembly and honing of the mating surfaces several times, I find a short but perceptable grit in trigger takeup right before reaching a smooth but light 4lb. trigger pull shelf. I have exhausted my patience as I have run tolerances in the trigger group to there end looking for an elusive solution with little improvement. I keep feeling that there is something small I am overlooking. Help!!! DAY
