It takes some gunsmithing so if you are not competent or have never even taken your Glock all the way apart, you may want to hold off on this for a while. I don't claim to be an expert but I know the risk at hand and I have done a lot of gunsmithing of my own. AR15's, Glocks, XD's and I am sure I am missing some. It requires removing material from the frame. I know some people will hate me for doing this and claim that the trigger is perfect the way it it. Well, I just hate leaving stuff alone and since it is my back up/extra gun, I figured I would try something I haven't really seen a lot. I tried looking it up on the internet but didn't come up with much other than the big names that do it themselves and don't have any how to's. It really did work out great and the only modification that you are doing to the gun that can't be reversed is a small 3/32 sized hole in a part of the frame that doesn't really make a difference. The trigger bar will be messed up as well if you want to put it into another Glock so you need to get another one for a back up if you wish to put it back to stock at anytime. If done right, all safeties will work. If you have any questions, just ask. I know it doesn't look pretty where the pin is, but the super glue kind of makes it look all crappy. It is nice and solid because the pin isn't long and doesn't move if I put any pressure on either side. It's getting late, pictures tomorrow. Good luck.
