G10 is a material made from layers of fiberglass and epoxy resin pressed together under enormous pressure and heat. The resulting material is very light-weight yet incredibly strong and impervious to all oils and chemicals found around firearms. Hogue's G10 grips are precision machined from the highest quality G10 material available to exacting specifications and are designed for a lifetime of use. This model has a black finish and is compatible with Sig P938 with ambidextrous safety.
