Was lucky to find a 4" with target sights at Allens Armory years ago. Had it reblued to take it back to the way it looked new. Nice guns, shoot great. Yours is the best fighting revolver out there. Being about the same size as the model 19 makes it easy to conseal. Enjoy your MR73 and head to the range to give us a report. Wood grips come up for the gun on eBay, there were 2 sets recently. Larry
