If this is a .38 cal (check the markings on the frame and barrell) it is chambered for .38 caliber. If it is a Police Positive ammunition would be the .38 PP If it is a Police Positive Special you could use .38 PPS Check with any reputable gun shop/dealer or range and they'll give you the information you need.
