Hogue rubber grips are molded from a durable synthetic rubber that is not spongy or tacky, but gives that soft recoil absorbing feel, without effecting accuracy. This modern rubber requires a completely different molding process than ordinary neoprene and results in a much superior grip. The material used does not come apart or deteriorate and is resistant to all solvents and oils used around firearms. Hogue Grips give you a lasting precision fit and durability that will provide years of dependable service. Fits Sig Sauer P220 Full Size.
