I thought this might be a joke. But sadly it is not. Bungee Holster is a hair scrunchie made a little bit longer and is used to strap a pistol to your belt.
Now Bungee Holster does address safety with regards to using this holster. He recommends that you do not carry chamber loaded since there is no real trigger guard. If you put the gun between your pants and belt, it might cover the trigger but it is not guaranteed protection like a traditional holster. I have issues with carrying chamber empty. However that is a long and sordid debate. Only you can choose for yourself how you prefer to carry your firearm.
