Welcome to the XD club! That immediate improvement in your shooting is no accident - the XD’s grip angle and low bore axis really help with natural pointability. Which model/size did you go with?
If you’re coming from an RXM, you’ll appreciate how the XD’s trigger smooths out after about 500 rounds. Try some 124gr NATO for break-in; it loves that extra snap.
What’s been your favorite ammo so far?
