Pasting from this interview thread since it's relevant to this topic. Indeed it seems to be selling well in Europe
interview with Ricoh Imaging General Sales Manager for Europe - PentaxForums.com
"
One of the most important products of our group is the Ricoh GR, the ideal device for street photography. We launched the Ricoh GR III 6 months ago and we are enjoying an extraordinary success: compared to the sales we made with the GR II we have had an absolutely incredible jump, especially in Europe where we have multiplied our sales by 7 or 8. It's therefore one of the pillars of the group today and one of the areas Ricoh are investing heavily in. In the future, many developments in the GR range are to be expected."
