Pistol Holsters are generally designed to offer protection to the handgun, secure its retention, and provide ready access to it. The need for ready access is often at odds with the need for security and protection, so the user must consider the individual’s needs. Choosing the right balance can be very important, especially in the case of an air pistol holster, where the loss of the air gun due to insufficient retention or protection could result in serious injury. Holsters are generally designed to be used with one hand, allowing the handgun to be removed and/or replaced with the same hand. To be able to return the handgun to its holster one-handed, the holster must be made from a stiff material that holds its shape so that the holster won’t collapse when the object is no longer inside to give it support. Holsters are generally attached to a person’s belt or waistband or clipped to another article of clothing. Some holsters, such as ankle holsters, have integrated support. Other holsters may fit inside a pocket, to add stability and protection to the handgun, keeping it more reliably secure and accessible than if it were in the pocket alone. Holsters are generally worn in a location where they can be readily accessible. Common locations are: at the waist (outside (OWB) or inside (IWB) the waistband), behind the back (small of back (SOB)), at the ankle, at the chest (in an elastic belly band or shoulder holster), or on the upper thigh. Holsters are sometimes contained in an external bag.
