Your welcome. I'm sure there are vendors with stock left, but from pics/reviews I've seen they have large slotted screws and I've read nothing about a bf pin. I was actually going to order the SXK version from a trusted vendor here, but he ran out of stock the day before. He made a post on a different site that they discontinued production, which pretty much explains why I couldn't find one anywhere. I just ended up ordering
SKU 4379400 for myself.
