There is one (new 1980 production, of course) listed on gunbroker.com for a while.

If you can talk the price down to $1500.... this one has been listed for months.
From description, I feel the seller is a very honest guy, way too honest... "Not suitable for .45ACP" -- probably this sentence in description caused this gun hanging there for long time -- but actually, all of them could have this potential issue, this seller just unnecessarily emphasized it (probably some viewer asked him?? God knows) -- the new 1980 guns were not made for shooting. It's for collecting only. Sounds like a headspace issue, that's fixable by gunsmith.
