Not something I'm looking for (now), but I do know how rarely these full size stainless single stack 9mm gems turn up...
Summit Gun Broker [just Google them - not sure if I'm allowed to post a direct link] is showing a batch of 3906s in stock. These are the late production variants with Novak fixed sights for $439.
Note: I have no financial interest or personal relationship with SGB. Just a pointer for fellow 3rd gen fans...
Also just posted a batch of 3953 ($425), 5946 ($325) and 639 ($330/365/395) pistols.
