I can't get J. J.'s website to open for some reason. The last time I looked at his service price list, putting a fixed pin gun back on face was "from $250.00", and a replaceable pin gun was "from $350.00". Replaceable pin guns are usually more expensive to rejoint because a new pin must be made, as opposed to just tigging up the hook and re-fitting. Marrakai is right, the cosmetics can drive the cost up with some replaceable pin guns. However, with some top grade guns, the engraved, slotted end that you see isn't the pin itself, but a threaded cap, which simplifies pin replacement.
