These are aluminum grips. Not bad.

Edward, Black Aluminum Grips. The CZ 97 B is the more substantial .45 ACP big bore brother to the CZ 75! Operationally identical to the CZ75, the 97 includes a screw in barrel bushing, loaded chamber indicator and double stack magazine. It has a hammer forged barrel and slide-in-frame design for superior accuracy and better recoil control to keep you on target. It has an extremely smooth double action trigger pull and a nice crisp single action trigger press. The grip and controls are ergonomically designed and with slim aluminum grip panels it's comfortable even for people with smaller hands. Sporting a manual safety and three dot sights with a fiber optic front sight, the CZ97B is a great every day carry option. Its advanced design and superior materials give this pistol great corrosion resistance and a long service life. The CZ 97 B is a reliable firearm built on a trusted platform that has been proven to be a great defensive option for home or carry at a price you can afford!

New features for 2013 are thin aluminum grips and a fiber optic front sight.
