he VZ 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. These are attached with the included T-15 screw. Note: These are for the N-Frame Square Bottoms only
