I agree with WR Moore, a thick sturdy belt is the foundation for waist carry (concealed or open). You want your holster and pistol grips to be exactly where you expect them to be. With Texas adopting open carry, I no longer worry about exposing my firearm.

Also, at 6' 5" and 225 lbs, most people aren't checking to see if I'm carrying. And if they do check, they'll just see my S&W Model 15 Combat Masterpiece, assume I'm a cop and walk away.
