A golf putter is disclosed that includes a shaft and a head secured to the shaft. The head includes a forward portion that defines a face, and the head includes a rear portion positioned rearward of the face. The rear portion may have the configuration of a ring structure. Whereas the forward portion is formed of a first material, the rear portion may be formed of a different material with greater density. In manufacturing the head, the rear portion may be formed and then placed within a mold having the shape of the entire head. Molten first material is then introduced into the mold to form the forward portion.
