I have been thinking about getting this for my Glocks and wondering every body's input on them, I searched and only found one thread on it. This is the one http://www.lonewolfdist.com/Detail.aspx?PROD=1008. I am afraid to do permanent mods to my Glocks. It looks similar to the new Glock Gen 4 mag catch, though I know Lone Wolf had this a lot longer. Any opinions, comments?
