I would agree with the previous posts that an updated M12 would be a grand idea. But I would take it one step further and go with a round butt M15. A rear sight similar to the new UC series or one that was used on Night Guard line mated to a XS front would be ideal. An upgraded action, 2.5 inch barrel, round butt, no lock and a durable finish would complete the package. The demand for a quality carry revolver is stronger now than any time in the past 30 years.
