Both the standard lug 627 (SKU 163357 MSRP $1,003 42 oz) and the 627 Pro (SKU 178014 MSRP $1,059 41.2 oz) have MIM parts. The 627 has these extras: chamfered charge holes, moonclip ready, 'tuned action' or Boss mainspring(?), custom barrel & recessed crown,and a spring-loaded front sight for fast sight changes. Both are great revolvers.

Love my 627 Pro... see my picture - it looks/feels great with the Ahrends Retro Targets.
