Sir Atlas, Thanks for your information. I used the Eeman teach upgrade kit, but polished and followed your methof so an SP-01 Shadow. DA went from 9lb 15oz to 5lb over 5 shot average SA went from 3lb 8oz to 2lb 5oz over 5 shot average. But by far the best thing is all grittiness is gone from doble action. Smooth as a baby's bottom. Cheers from Australia!!!
