New guy, maybe new owner. But need 2 get a price opinion first. Guy at work is trying to sell me a xd40 tactical with 5" barrel and green laser, forgot what brand laser though. he says about 150 rounds through it. Has everything it came with when he bought it plus 4 magazines and 100 rounds. He wants 550 for it. I think he's crazy. The gun is only around 510 bucks new. But it will be my first gun so maybe i'm crazy and thats a good deal. So, what do you guys think, should I snatch this thing up this week or tell him find another guy at work to screw over? Thanks.
