I am always curious as to what other people run when it comes to competition use and carry. I don't run an XD in competition personally, but a lot of folks I shoot with do. The must haves from them seem to be a nice Powder River trigger kit, Talon Grips and Dawson Precision fiber optic front sights. Springer Precision guide rods and base pads are popular as well. What are your must haves?
