I picked up a Glock 19 late last year and recently went to install a set of sights.I got the rear on ok,but I'm having a hell of a time removing the front sight.Unlike the Glocks of ten years ago,which just had the plastic units you could remove with a pair of pliers,mine has a better,all steel unit with a screw/bolt holding it in place like most aftermarket sights.The problem is that none of the glock tools I've tried will clear the area around it's head and get a tight enough bite to unscrew it.Has anyone else had this problem?Thanks
