Nice! I usually only see USA Magazines/no names/rusty rejects. You did great!
However a while back while away at a small town with the War Dept I stopped at a small gunshop and found these two 4006 mags just after buying my 4026. I remember seeing some single stack mags there too but wasnt really interested at the time.
Fast forward a year and I now have a 3914 from a Forum member, and a good excuse to go back. Would you believe the mags were still there?
I don't recall exact prices but they seemed pretty reasonable, though nowhere near your enviable price.
Added: I think she might be wondering why we end up overnighting there so often...
