I've seen two now, this one is "sold" but there is a current ad on there for what looks like the same thing. I think someone bought up a couple from the recent Ohio Ordnance Works' imports, did some work on them, and now are selling these for 3 times the importer sale price. https://www.gunbroker.com/item/791549881 It might even be a good deal considering how much getting custom work would be.
I would not sell my alloy Hi Power but did a little customizing to meet my needs. I replaced the spur hammer with round, better safety, neat grips and topped it with Cerakote
