Ok, Im getting frustrated with this pistol. I tried pan lubing some today with some lube I made a while back. Cant remember exactly what was in it, but it consisted of vasoline, parifin, and moly grease. Better, but still some leading near the muzzle. I reduced my loads to 4.2 grains of unique and still some leading near the muzzle. If I go any lower the slide wont always lock back on an empty mag. I don't know what else to try.
