The 625JM and 627 Pro take the same 0.250" height HiViz designed for the 629 Classic DX, ie, spring loaded sight mount. No adjustment was needed when changing the 625JM's stock gold bead Patridge sight. A couple of clicks upward, if memory serves me (It was 5/08!), were needed to get the 627 Pro 'on' at 12-15yd with 125gr JHP .38 Specials at ~900 fps (Montana Gold bullets over 4.2gr Titegroup.). My HiViz sights came from Brownells.
