Colt Detective Special / Diamondback (D Frame) Black Rubber Monogrip
Hogue rubber grips are molded from durable synthetic rubber that is not spongy or tacky, yet provides a soft recoil absorbing feel, without affecting accuracy. This modern rubber requires a completely different molding process than ordinary neoprene resulting in a much superior grip. The flexibility of materials and molding process has allowed Hogue to produce rubber grips with features that out perform all other makes.
