With the grip bedded and backstrap approaching 95% its time to finish the trigger guard. Rather than fill the offset front screw hole (offset slightly forward of the matching threaded hole in the bottom of the frame) I decided to use it. That way there is no solder line to show through the bluing of this steel trigger guard. I usually do the opposite on a brass trigger guard as the solder line, if the plug is fitted tight, is very hard to see on brass.
So, fill the hole in the ruger frame with its original 6x40 screw, lock tite and stake the end after filing flush in the cylinder window.
Make the screw head, on the underside, crescent, to additionally lock against rotation when the new 6x48 front screw is installed.
Drill, tap (6x48) the new front screw hole and install the trigger guard. Done.
