Changed to flat triggers on 9 each P226 and P220s, 3 are Amory Craft and 6 are Grayguns. On the west german P220s I lost useage of SAO safety on 3 of them, 1 is Armory Craft and 2 are Grayguns. Also changed to more aggressive G10 grips on all. Have tried several times to correct the three, but no luck. Love the way they shoot and feel, but need to get safeties functional again on the 3. Any ideas?
