Just ordered one of these and installed on my SP-01. Took some fitting as the rear of the dovetail needed several strokes from the file. Love the sight picture.
It does sit a little high (as in space between bottom rear of sight and slide) which is probably normal but wanted to add it took a 6.0mm front sight to get POA/POI vs the recommended 5.5mm. Has anyone else found this to be true?
