They are all over gunbroker for under 800. There's a REAL nice grade A for 750 right now, but it's the one with the warning statement on it, not quite as "ooooo aaahhh" as the other ones.
Those must be PSPs, not the P7M8. PSPs are way cheap because of all the border guard imports that flooded the market. A lot of them have a huge mill mark on the slide where some kind of logo or internal serial number was milled off the slide. Still a decent gun if you can tolerate the heel release, and the fact that they don't have a heat shield.
Decent P7M8s are generally always $1200+ Not that long ago when they were still in production, the new ones were like $1250-1300, and they had the ugly trussville warning and import marks on them.
