Are you seeing a back-side load of used XD pistols on the market? I am. There's a flood of them.
Over the past years, a lot of guns were being purchased with plastic money. With the economy the way it is, it wouldn't surprise me in the least to see some of them being sold off to pay for the essentials now that Mom or Dad just became unemployed. That is how some folks function....spend it when you got it, sell it when you don't.You sell a lot of anything, some buyers are going to get tired of what they've got, decide they don't like it after all, or have a family emergency requiring them to liquidate some assets and bingo, it winds up in the used case.
I wouldn't read too much into it...
