I shoot IDPA at a local club and am planning on joining IDPA and competing on a regular basis. My question is, does anyone here use the XD holster in competition? Is it even approved for use by IDPA? I currently use the XD paddle holster and it works perfect for me, but I did not see anything in the rule book about the use of paddle holsters. If you are not using the XD holster, what are you using?
