Shoulder holsters mean a gun holster under your armpit. However, they have become a fashion statement more than a carrier for your gun. Wearing shoulder holsters has become a part of your outfit.
As leather products are a delicacy and not everyone knows or preserves these products well, there is little profit in selling these holsters. Unlike leather bags or wallets, these holsters are not hot-selling items. But since Thomas Shelby has been seen wearing it in Peaky Blinders, the show’s fame made it a selling point. Everyone who loves Tommy Shelby wants to have a shoulder holster just like him.
