Hogue rubber grips and panels are molded from a durable synthetic rubber that is not spongy or tacky, but gives that soft recoil absorbing feel, without affecting accuracy. To retain their shape the grips utilize a modern, lightweight synthetic insert that chemically bonds to the rubber. This prevents them from delaminating or coming apart. Features include orthopedic hand shape and proportioned finger grooves. Fits Sig Sauer P220 Full Size Pistols.
