I saw the Mann site and those other reviews last week (I've been trolling the R51 hard for two weeks, now). I still have yet to see anything beyond a basic field strip. I really want a look at the safety and trigger system, and the surfaces the locking block surfs on.
I'm starting to wonder if the binding/no binding issue people are seeing is due to the upward and downward cam surfaces controlling the block too tightly. That is to say, when racking the slide, the upward cam pulls the block up into the downward cam surface a bit, resulting in binding. It'd be like a pin riding in a tapered slot that gets ever so slightly too narrow at one point before flaring out again. May not truly cause interference, but would make the pin's travel more difficult at that spot. From what I've read, the locking block and slide interaction is actually pretty tightly choreographed in the firing cycle (and therefore vulnerable to poorly executed machining)
