The new ESP Overmolded Pistol Grip from Exos Defense is now available. This grip features a polymer core that is overmolded with low-tack elastomer (rubber-like plastic) to offer the right amount of grip without being tacky or abrasive. The grip angle is similar to the traditional A2 grip but the backstrap is more rounded and it has a beaver tail that fills in behind the receiver to promote better trigger finger placement. It has very subtle finger grooves and a slight palm swell with additional peddled texturing on the swell.
I have one of these in hand and it is very comfortable. It is currently only available in black but a full slate of colors will be offered. Check out the ESP Overmolded Pistol Grip at Exos Defense.
