The Ergo Grip is the original ergonomically designed grip with SureGrip textured finger grooves as shown. It has an integral rear upper extension that helps support the web of your hand. It is comfortable, helps prevent fatigue, and aids in controlling the weapon even when wearing gloves. The right and left hand models have a built in thumb shelf that helps maintain a consistent grip on the weapon. The textured finish provides a superior surface that minimizes slippage. The Rigid Polymer and the SureGrip overmolded rubber versions are both virtually impervious to oils andsolvents used on firearms.
