Big grip, not for me - Ergo Grip AR15/M16 Ambidextrous Tactical Deluxe Rifle Grips

I have had an Ergo grip in the past and liked it. I decided to try this deluxe version and immediately was unhappy. There was nothing wrong with the product physically, I just think the grip is a poor design. It's very fat. I kept loosing grip and would almost drop the rifle. The grip is slippery as well. The shape isn't quite right for my hand either. So it's to fat in the hand, a weird shape and slippery, a bad combination. I have the CAA version of the Tdi Arms AR15/M4 Interchangeable Firearm Grip Optics Planet carriers and this grip is great. It fits my hand like a glove. I'm going to try the FAB Defense Ergonomic Pistol Grip once Optics Planet processes my return of the Ergo grip.
