100-400 USD
Actually I think it's more like $200 to $450. In "normal" condition for a used gun, with some wear on the edges and maybe a little nick or blemish here or there, say $350-$400.
If it comes in the original plastic Glock box, with the owner's manual, bore cleaning brush, etc. then it should be more like $400 or $450. If it comes with more than 2 magazines, add about $15 for each additional magazine, and keep in mind that some magazines for these guns were made during the "assault weapon ban" years and will only hold 10 rounds. That's a few rounds less than they were designed to hold.
I can't imagine anybody selling one for $100 unless it was something that had been run over by a train or used as a big sinker for a salt-water fisherman. Even a heavily used Glock with lots of wear and some scuffs and nicks on the finish ought to be worth $200 or better.
If it's a stolen gun, it might sell on the streets for $100. Avoid that situation! Never buy anything you think or reasonably suspect might be stolen property, especially a weapon that might have been used in a crime. What happens if one day the cops find that gun on YOU and link it back to some robbery or murder? I once had a guy offer to sell me a Glock 9mm for $50, but he told me right up front it was stolen, recently taken by breaking into the parked car of some off-duty cop.
