Check with Lou at Shooters Discount. He still had some LE trade-ins I think. They were under your budget but no mags. I bought one of them myself a few weeks ago.
Moderate holster wear. Mine didn't appear to have been fired too much though and functioned smoothly at the range the other day. Standard Glock dot and box sights. Pics after I gave it a good cleaning:
ETA: The lighter spots on the side of the slide in pic 1 are wear on the finish.
