I have a 686+ (686-4) and when shooting it DA after the cyl stops turning and befor the hammer drops it has a tight spot. so after cleaning it and lubing and dry firing it with the cover off i see that the hand is rubbing between the cyl and the frame. it looks as if the cyl needs to turn just a little more? if you look at the pictures you can see just a little of the top of the last notch on the extractor sticking out. is that suppost to be that way? any info would be great Thanks
