I ordered one of these http://www.lonewolfdist.com/Detail.aspx?PROD=7373 for my Glock 17 Gen 4 and it should be here Tuesday. Will I been looking online trying to figure out how hard they are to install. Google and Bling both failed me looking for any information on this. Could someone link me a sight or just give me a basic Idea of what I am looking at as far as getting this installed. Thanks Guys.
