Things I liked:Turns the Alfa into a serious competition gun by fitting your hand better and having a palm shelf for the extra support. Incredibly easy to swap out with the ambi grip. Just loosen a nut that fits over the air chamber in the grip, and pull the grip apart in to it's 2 pieces. Can be swapped in less than a minute. Things I would have changed:Add the ability to adjust the angle of the palm shelf as well as the height. Make it in different sizes as well as left-hand. This is the only area where it might not be best for you, depending on your hand size. My right hand is 7 1/4" long from the base of my palm to the tip of my middle finger, and 3" wide across my second set of knuckles. What others should know:If you want the Alfa to be the best it can be, you've got to have this grip. Please see my full review of the Alfa on it's info page. Good Luck, See Ya Shootin".
