I have several XD's. Actually 3 overall. I have two XD 9mm service models. One all black and other Bi-tone. Both have about 700 rounds through them. Also have a xd sub-compact. Everything is in 9mm. I also have a TrP which of course if 45. So, here is my problem. Since I have two service models, should I sell one of them and get an XDM? I actually have thought about selling the Bi-tone here on the xd site but really have not seen many of these move lately. I am having a hard time with this because both of my service models have been perfect. Shoots everything I put in them and very accurate. So, would you try to sell one of them or just keep them? Tough decision.
