I have a friend who is wanting to sell a XD9 tactical that is completely rigged out for ESP division of IDPA. Powder River competition trigger kit, Dawson Precision adjustable fiber optic rear sights, DP fiber optic front sight (.100" wide). holster, mag pouches, and 5 mags. He has no clue what price to ask and neither do I. I know it's hard to recoup money spent on improvements so kinda lost. Any ideas what the gun would be worth?
