You need a true gun belt - a belt with two layers of leather bonded and sewn together so it resists twisting.This spreads the weight of your gun out over a larger area and prevents sagging, pulling and droop.
When you draw your gun, the holster and belt should not pull up with the gun, but stay stationary.
A true gun belt like ours will make you feel like the holster and gun are part of you, not some bothersome appendage flopping around on your waist. The gun belt is the foundation of comfortable carry.
Easy Way to Put On a Gun Belt (below):
The best way to put on a stiff gun belt is to avoid bending the tail of the belt back to the right and pulling. Instead, put the tail through the buckle, grab it with your right hand and move hands in opposite directions until you reach the hole you want. Same goes for taking the belt off.
