The Reckoning will come with the Micro Snaplok (IWB clips) and the OWB Wing clips. Beyond that, the Accomplice adapter is if you plan to add the Accomplice Mag carrier to the holster. The Polymer clips are an IWB option instead of metal. J-clips go behind your belt, rather than over the top so they're more hidden from view. V-clips attach to Velcro-lined belts. And the CB concealment claw attaches under the grip of the firearm allowing less printing since it torques the grip toward the body.
