Stripped screw removal (RMR from pistol)

Stripped, broken and sheared screws are the bane of any gun owners existence.  Often problems are encountered from a myriad of reasons ranging from poor quality fasteners to damage from the firearm itself. In my shop, I’ve noticed an increase in Trijicon RMR equipped pistols that have had stripped screws.  This is how I take them out.

I ordered the following items from Brownells for this project:

Before working on the slide it needs to be secured.  I like using a Brownell’s Multi-Vise with a set of rubber jaws.  I find this protects the finish as it firmly holds the slide.

Encountering a stripped screw on an RMR is a frustrating experience.  Typically the sight and pistol it is mounted on is quite expensive.  Beyond looking sloppy, a stripped screw means the battery cannot be changed nor can the sight be maintained.  Stripped RMR mounting screws seem to be fairly common.

I like to drill off the heads of screws like this.  The stripped portion of the screw is centered and acts as a guide.  I’ll select a drill .010-.030 over the major diameter of the screw.  In the case of the RMR, it has #6-32 screws with a major diameter of .138″, a #25, 24, 23 or 5/32″ drill bit should work well.  I actually prefer to use a hand drill over a mill for this operation.  I feel it prevents me from cutting too deep into the screw.  I go slow with minimal pressure at a low speed.  When the screw head pops off, I want to be able to stop immediately.

When the head pops off the screw (above), you’ve drill far enough.

The sight is simply pulled straight up off the mount exposing the shank of the screw.

I like to grab the screw hank with a small pair of pliers and simply back the screw out.

With the screw out the job is done.

This slide is ready for new screws and an RMR!

I use a similar technique for removing stripped screws from rings and bases.  If you get jammed up, this may help save the day.
