Gun Slings are straps or harnesses used when using firearms, which allow shooters to carry firearms more conveniently (generally used for long guns, such as rifles, carbines, shotguns, or submachine guns) and allow the firearm to provide better support and stability can even help shooters improve their hit rate.

Different types of gun slings have their advantages and disadvantages and can generally be divided into several categories.

Two-point sling

This design has only two attachment points to the gun, which connect to the front and rear ends of the weapon, allowing the shooter to carry the weapon on their back, in a sling, around their upper body, around their neck, or over one shoulder. Some dual-point gun slings, if designed properly, can also assist shooting.

Ching sling

The program gun sling is a tactical rifle sling invented by Eric S.H. Ching. The shape of this gun sling is very prominent. Its original design is to stabilize the rifle and make it an auxiliary tool for shooting. And minimize the impact on shooting. However, since it is mainly suitable for shotguns, sniper rifles, and other rifles that require frequent standing and precise aiming and shooting, this kind of gun sling is rarely seen on other types of weapons.

Two-point quick adjustment gun sling

This kind of gun sling is developed based on the traditional two-point gun sling, but it has the function of quickly adjusting the length of the gun sling through the handle to adapt to different purposes. It is also very popular and well-reviewed in the tactical shooting community.  This type of gun sling also has disadvantages. For example, shooting with a double-point sling turned over the shoulder is a challenging action because it often strangles one's neck and makes it difficult to breathe. In this case, either loosen the gun sling or fully extend your arm and let the gun sling come out.

Three-point sling

The three-point gun sling has very obvious characteristics. It is more like a harness that binds the gun to the shooter, allowing the shooter to release the weapon and free his hands to complete other tasks without worrying about the weapon falling to the ground. Because the three-point strap will keep the weapon on the shooter's body, the long gun will be easily accessible when it's time to switch back to the primary weapon. This type of gun sling design consists of a strap that goes around the body, and two straps that connect the front and rear of the weapon.

Single-point sling

This gun sling design is most suitable for short-term combat use. Because the single-point strap has only one way to wear it and cannot provide the same long-term anti-fatigue weight support as other gun slings, simply put, if you wear it for a long time, you will feel more tired than a double-point or three-point strap.
