I didn't get either one?

The reason I asked about a fair trade value is because I was trying to trade the pistol and holster for a well set up Bushmaster M17 (bullpup) and $500.00 He just wants to trade even up - I've had this pistol for a long time, so I'm not in any hurry to trade it, especially if I'm going to get the short end of the stick.
