I paid $599+tax for a NIB full-size .45 USP with 2 12-round magazines (gray frame/black slide, Variant 1). IIRC, these were $672 wholesale before shipping in the last CDNN catalog.
I saw a 9mm with high-caps and night sights for $581, etc. (The "Tactical" and "Expert" models were higher, but still well-priced IMHO).
I didn't go looking for these. Heck, the last time I fired a friend's .45 USP (I've never owned one), I remember it feeling way too big in my hands. Since then, I've made myself learn to shoot my G21s well - I guess that made a difference, because the HKs felt much better in my hands yesterday that I ever remember them feeling.
Ironically, I went in there to buy the new SA XD-45 (which are selling down here for $549+tax). When I saw the .45 USP for only $50 more, I couldn't pass it up (I didn't even notice/ask if they had the XD in stock...).
