Regarding Hapworth's remarks about no replacement sights available. Does this mean then that the dovetail slots are peculiar to the PRO and don't match up with anything else? If that's the case I wouldn't expect a lot of interest in the aftermarket community. Not likely they'd have a production run that fits only one pistol. I asked about that some time ago and nobody was really sure at the time. It's the one thing that held me back from buying one.
