I've been looking at a couple of 659's on the Internet. There seems to be two models, one with conventional rear sights and another with what look to be "ears" on the side. In other words the rear sight is protected.
The question that arises are which one had adjustable sights for windage and elevation?
Obviously one would have to be adjusted with a drift with no elevation change but I can't find a picture that shows if the protected sight has any adjustments.
I guess there are variations of that model so a quick education would be appreciated.
Thanks,
