I called Ruger, they are sending me a screw but wanted me to take all the screws out and check for a short one. I hope I can do this, I have ocd bad when it comes to a new gun, once I have one for a while I can strip them down without worry but I have a hard time taking apart a new unfired gun. I just want to let it go and go get another that isn't messed up, I know that sounds bad but I have always been this way on a new gun, if something ain't right I just don't want to keep it. After its been shot a while tho I can do a complete tear down and put back and it doesn't bother me, its just on a new gun. The lady said I have to check every screw because if the short one is somewhere then it might not hold and fall out. thanks
