I have been looking at them for a very long time. I love the look of them with the flutter barrel and the much better sights. I had a 640 and sold it and then an M&P 340 that I had for many years. I traded it away for a 649-2 because it was much nicer to shoot than the 340. For those of you who have the 640 Pro, how do you like them? I have heard reports that they don't shoot to POA/POI. Not sure what they are calibrated for in terms of load. What has been your experience???
