I just got my mag today and it both looks and works great. The only thing I need to do now to make it into a side arm
is to drill and tap two holes for the asa in the back part of the rail. I have drill bit and I have the right size taps is there anything else I need?
Basically my plan in so take the rail and clamp it to my workbench. Drill the holes with a 16 volt drill and then hand thread the holes with the tap applying copious amounts of WD-40 to keep from messing up the rail and breaking the tap.
