High quality construction. Precision fit and locks down solid. I didn’t really think it’s practicality through though, and probably won’t use it. The only place it can fit is forward of the button/switch for the light, and there’s no way to really actuate the light button while using the grip. Ergo, the button becomes useless if you’re going to use the grip and the light can only be used with the rear dial in the constant ON position. I’d give it 5 stars if the design incorporated a way to practically use the button feature on the light it’s designed to go on.
