Start with one .015" (pink) shim and adjust from there, after a first group. Amount of needed shim will vary, depending on load and particular barrel. Approximately, each increment of .002 to .0025 of elevation shim will affect bullet impact by 1" at 25 yards. The dovetailed XD front sight may need to be fitted to your slide. The XD-DD rear sight should drift in with a minimal amount of tapping with a wooden or plastic mallet.
