The VZ 320 is the smoothest grip VZ produces in their vast line of grips. 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. Designed specifically for the Ruger SP101. T-15 Screw Included. Mfg: Vz Grips
