Yea I know it sounds lame, but its the dumb questions I ask that save me time and money. I have a standared 7 round Kimber mag that has 2 pre drilled holes already there. I have a factory kimber extended base pad with 2 screws. I wanted to know if I should run a #43 tap through the holes before mounting the base pad or just run the screws straight in with out tapping the holes, and should I use some blue, or red lock tight just in case.
