Ironically, since that happened, demand for them went back up. It's like with the OD framed Glocks. When they were available, no one really cared for them, but when they were discontinued, morons were willing to pay up to $700+ for a used one.
That RTF isn't my primary carry piece (I do AIWB) because it's pretty abrasive. The times I have, I wrapped it in black hockey tape. I bought this one when my other G19's slide went **** up (Glock replaced it free of charge). This one was a like-new police trade-in I got for $389 last year (with 3 mags and factory night sights). Trade-in G19s (let alone in good condition) are pretty rare, which is why I jumped on this one.
You can still find them used or from old stockpiles that are laying around.
