With the knowledge acquired in this post and others, I just finished an SP-01 (safety) that I have been shooting for years. Thought it had gotten pretty good with just the wear in process but thanks to David at CGW for parts suggestion and sharing his valuable time to answer my questions, I now have the range gun I always dreamed about.
It went so well, I reworked the wife's SP-01 Tactical with more parts from CGW...this will ensure I get to keep my pistol :-)
Thanks again to everyone for sharing your knowledge on this forum and thanks again to David at CGW...
