Details matter, and they often help to distinguish the difference between good and great work. In this post I’ll be finishing a few details on a custom Colt Series 80 Enhanced Officer’s ACP.
For reference purposes, a schematic of a 1911 pistol can be found here.

I ordered the following tools from Brownells to complete this project:
The spring plug on an Officer’s model 1911 typically has a slot that is engaged by a screwdriver as shown above. Note the slot on this plug isn’t perpendicular.
Flipping the slide over, note the tab on the bottom of the plug which engages a slot. This means the plug can’t simply be rotated straight.
I secure the plug in a multi-vise and use a small file to straighten out the slot. I also remove the factory checkering pattern from the end.
The plug is then rested on a parallel in the milling machine vise.
A 3/16″ 2-flute solid carbide end mill is used to cut the golf ball pattern. Each cut is .015″ deep and spaced .100″ apart. Subsequent rows are staggered .050″ on the x and y axis.
The finished plug looks great. Note the corrected slot and the newly applied golf ball pattern matching the rest of the pistol.
