The oversize release button has a double meaning to it. Not only is it taller, but also bigger on top. Bigger top isn't causing pain to your thumb when you press on it and the taller idea is for you to reach it easier. Button is a perfect match to your gun, it is black in color and IT DOES come with the spring and bushings. This button is design for quick and more practical magazine release, not to make your gun more sexy. Button does stick out if you still have the original grips. If you interested in purchase, don't hesitate, you'll love it. I know I do.
