The 320 is the smoothest grip we produce. Minute mill marks are left behind from the CNC machines and are left unpolished. This gives the grip just a hint of texture, which makes for a very comfortable grip. They are visually appealing as well. Since there really isn't any pronounced texture, you can see the bold layers of color in the laminates we use. a TEXTURE: Smooth/Mild a USE: Concealed Carry, Soft Hands, Display a MATERIAL: G10
