Below is the unlock block for my XR9-L. The piece to the right of the block is the raised ridge of the block that somehow sheared off the block while I was shooting the L last sunday. I didn't notice any issue at all while shooting. It was only afterward at home when I opened her up for cleaning that I saw the damage as the ridge fell free of the gun as I lifted the barrel from the slide. I am honsestly bewildered about how this happened, and am more than consternated since I have no spare unlock block for the "L". Bond Arms appears to be ravaged by flu which seems to have crippled its customer service department. BUMMED OUT DUDES!
