    GX4 Aluminum Pinky Extension

    Excellent product. Game changer on grip performance. Solid construction, great fit and finish and looks like it is part of the gun.

    Priced a little higher than some others. BUT WORTH IT !!

    This is a nice little mag extension. Went with the aluminum for the finish and added weight on a smaller platform like the GX4. Doesn't add as much weight as I had hoped but definitely assist those with larger hands and wider fingers. Pushes your hand up slightly because of the cant of the extension which works great and aids with control. A little excess play with it fully seated if not for that it would have gotten 5 stars as it looks good and does what you’d expect it to. The install is super easy and I had no difficulties swapping this out for the stock flush base plate. My unit did come a little cosmetically flawed. Similar to the one in the picture the button hole has small scrapes in the inside most likely from the machining process. Overall finish is still nice and feels good in the hand. Worth the extra coin compared to the plastic alternatives !!
