I just picked up a used HR 622. It seems like a nice, well built revolver. The DA trigger pull is quite heavy, but SA is pretty nice. I got it out last weekend and it runs great. The only issue I have with it is that the hammer spur, in DA mode, is directly in the way of the sights! In order to see the sights, you need to actually start pulling the trigger. When the hammer comes back about 1/3 of the way, the sights come in to view. Please see the attached photos. If you look at the one with the wooden stick (which is in the sight groove cut into the frame) the hammer spur is actually about 2mm taller than the groove. I really don't like that setup at all. Is there something I can do about it? I thought about milling a corresponding groove into the hammer spur, so you could see through it. I considered buying a spare hammer to work on, should it not turn out, but nobody seems to have any in stock.
