I put a Hogue 18400 Handall grip on my EC9S. I haven't shot with it yet, but I really like how it feels. It is more comfortable and allows me to get a more firm grip. The finger notches are nice. I was worried that it would add too much bulk, since I pocket carry it in a Sticky Holster. It does feel slightly larger, but it is not a problem. It also stays in place in my pocket better because the added friction prevents the gun and holster from rotating in my pocket.
