Thank you to all who contributed to this thread. Bought an SP-01 two days ago, pulled it apart and polished everything with the exception of pulling apart the sear cage yesterday. Waiting till I get parts from CGW after Christmas. All the grit in DA is gone. Went out and put 250 rounds through it with out issue today. Loved it. BTW I have only been shooting for about a month and never had a gun apart before. This is great info.
Thanks again.
Matt
