ZERO PERCENT STEP 3 - DRILLING AND TAPPING THE HOLES

 

There are eight holes to drill, however if you don’t want a tac rail, then it would be five, and if you are using a standard Ruger barrel, then you would not need the pin alignment hole.

Drill List: :

5/16 (take down lever hole)

1/8 (ejector mounting screw hole)

9/64 (slot locator hole for slide stop bottom cutout relief)

#39 (ejector tab hole)

#31 (6-48 tap holes)
