I do not own one, but have seen a couple straight grip conversions that Keith Kearcher has done---they've looked very nice. His price list shows it costs ~ $375 plus engraving and bluing. If he'll do a straight grip conversion as expediently as his repair work, you can expect a very reasonable turnaround time.
