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. The flexibility of the materials and molding process produces rubber grips with features that out perform all other makes. It is molded with a reinforcing insert directly engaging with the firearm frame for a rock-solid grip-to-frame fit. The Cobblestone texture provides an efficient non-slip, non-irritating stippling pattern. This Monogrip model has a black finish and is compatible with Ruger SP101.
