If you look at other belly band holsters you will see that almost all of them are made from elastic. Unfortunately that is not the best material to make a holster from. It turns brittle after getting wet repeatedly, it has a tendency to pinch your skin and body hair resulting in pinches and pulls, and is uncomfortable against your skin.Sizing: The belly band holster measures 5 wide x 42.25 long and will comfortably fit a 46 diameter. To ensure a comfortable fit simply use a tape measure and measure the area you intend to carry. If around your waist simple measure your waist and so on.
