Advice needed

What is the best way to sell a high end gun? I’ve got one listed on GunBroker…not getting any bites. I know it’s not price. Just wondering how you guys go about selling a gun. I’ve called the local trap/skeet field, the local HS Trap coach. There’s always one or two who upgrade to a Perrazi or Krieghoff. I’ve got a Cesar Guerini Invictus Impact…same level quality, just not at their price points. Any advice would be appreciated.
