A great way to carry around a small gun or weapon is to fasten it to a holster. Holsters can be worn under the arm, or even strung on belts. The general material that is used in the making of holsters is leather. However, you will find many variants in the market today. It is even possible to string a holster on a saddle, in a vehicle making it an extremely useful accessory.
Evidently, one can identify the perfect holster by the weapon in use. Small guns or knives need only to be clasped and sealed to make it convenient for carrying around. Larger guns and knives need holsters to be more secure and hence will have more support. It acts as a safety net and secures the weapon in place making it less likely for injury through accidental movement. Blades and Triggers have a spectacular collection of holsters available online.
