For me this is a 'must-have' piece. The standard magazine release doesn't work well for me. The pressure point to press to release the magazine is far enough that I actually find it easier to use the smaller magazing release buttion on a Gen 3. The TangoDown magazine release works MUCH better for me than the factory version.
I put them on all my Glocks. Makes releasing the mag just that much easier, functions pefectly, reasonably priced, I highly recommend this upgrade.
