The VZ 320 is the smoothest grip they produce in their vast line of grips and do not incorprate any finger grooves. 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. T-15 Screw Included.
