Gun-belts must be Sturdy Thin and Lightweight

A stretching belt will allow shifting in your point of carry and that can be all the difference in a time of need. A good gun belt will hold your holster and handgun exactly where you want it and keep it there. ...

This is of importance because the vertical strength of the belt is what supports the holster and handgun. 

The vertical rigidity of a gun belt is vitally important. Not only does this keep the gun and holster where one means for them to be placed - important for concealment, comfort and security - but is also important because it's necessary for the draw stroke.

Gun belts prevent the gun and holster from sagging outwards, which may expose the weapon. A sagging holster and belt can also twist or catch when sitting down, especially in a car. A belt that isn't designed for concealed carry will often stretch due to the weight of your gun.
