I spent a lot of time smoothing out the trigger on that P6 and playing with Wolff main spring kits...I got a lot of the grittiness out of it, but could never get the DA pull down to a level I liked without introducing light primer strikes.
It was a wonderfully built pistol though, and probably the pistol I shot the best (in SA) apart from my P7 (also sold). What can I say...I'm really picky.
