How to Repair - Luger breech block wear- striker spring guide comes out

[DonVoigt]

This luger breach block must have been nearly worn through at the striker guide retainer, as after a few mags of ammo fired- it would not function any more!

Disassembly and inspection revealed the wear seen here and also shown in this thread:

The first three pictures are before repair.

I don't have the capability or ability to do a "good" small weld, so decided to fix the problem with a transverse pin inserted to replace the missing/worn retaining lip. I used a 1/16" pin, made from a drill bit.

Being too impatient to take the piece to my machinist friend to do the work in a "real" milling machine; I decided to do a trial repair with my drill press.

I used two 1/16" carbide drills because I broke one, they were not long enough to do a through and through, so I drilled from each side and then through both holes using a normal drill from one side. I was a little surprised I was able to pull this off, mill work would be much surer!

After the job, the pin required grinding and shaping to allow the striker spring guide to enter and turn as designed. This was done with a dremel and various bits. When finished the pin was locked in place using green penetrating loctite.

One can see the pin ends on each side of the breech block, and the pin body where it passes through the circular opening.
Bench function was ok, so then to the range, where 2x 8 rounds as trial worked just fine. I'll be firing more to determine the "durability" of the repair.
