I bought a minty Glock 20 for somewhere around that figure years ago with two pre-ban hi-caps when the the ban was still on. I was thinking of selling it recently to defray the cost of a Sig P238 so I brought it down to a couple of local shops to ask about consignment or trade in.
The first shop didn't want it either way saying that there was zero demand for the caliber and the ammo was scarce. The second shop told me that it was a $350 dollar gun and they get 25% on a consignment basis. I asked about trade in and was offered $175.00. My model 20 is still in really nice condition BTW. Probably not much more than a few hundred rounds through it.
So since those offers were unacceptable to me and I hadn't shot it in years I decided to get reacquainted and I bought a couple of boxes of 50 (ammo wasn't scarce after all) and took it to the range. After running the first couple of magazines through it I decided that I don't want to sell it .
BTW, I don't fault these brick and mortar establishments for offering me low $ on my Glock. They have rent, yellow pages, electric, staff and most of all inventory to pay for. They might have to sit on that gun for an extended period of time so considering the overhead there policies are understandable. Matter of fact I'm glad that he didn't give me a decent offer, I might have accepted it.
