I have a huge stock of these pins on hand. The company I work for needed these for another application (Non-firearms related) and the minimum order was huge. We used 6 for work, and I noticed how similar they are to the pin on my XD. I got to measuring, and they are identical.
The pins are made from heavy gauge stainless, much stronger than stock and look identical to the ones being sold by other XD parts suppliers.
They will be shipped in a USPS envelope, and I prefer paypal payment. My XD was black, and the pin was small enough to not stick out visually being stainless.
If they show up and you are unsatisfied, I will refund your money. I'm not making money on these, just trying to help out after I saw what some people are paying for these pins. I probobly have a few pounds worth sitting here. If you are interested, please e-mail me your shipping address, and I will respond with my paypal address.
