Those guys who live in socialist states usually pay more for a "normal to us other folks" 17 round pistol. When they intro'd their law,
the existing guns were grandfathered so the guys who had them at the time would still be legal. But, no more after that time.
The grandathered guns/mags (sometimes it's the gun and other times it's the mag capacity-depends which socialist state you live),
have not been made in a while now. However, I think this gun went for that price b/c it's serial number is AK747<-- hence AK47/AK74.
I just bet the guy who bought that G17 has a collection of AK's.
