I recently acquired a 640 Pro Centennial.
While the front is ok, I would like to replace it with something brighter, like a Night Vision type big dot tritium. The rear tritium can be blacked out, bit I would like a wider notch, so a plain rear sight without the tritium vials would be appreciated.
Has anyone changed theirs ?
