If you carry a gun you should have a gun belt but I am the only one I know who carries a gun here, that uses a gun belt. I prefer the instructor nylon types as I can get them in various thicknesses and they can be adjusted just right since there are not holes involved that force you into a set position. Take a look at the Wilderness Tactical line of instructor belts. I do not like the original instructor belt as I do not need a heavy metal buckle to attach a safety cord to. I get the frequent flyer belt with the polymer loops. Very lightweight and comfortable. I have three of them in different stiffness depending on which gun I am carrying. So nice that my non gun owning friends all ordered them for every day wear. I used to wear them before I started carrying too. They are just so easy to adjust moving from a sitting to standing position and you can get them just right.
The worst thing about growing old is that other men no longer see you as dangerous.
