That's the ticket! ...if they export to the US.

It also appears that the threads are larger diameter than the shank, which is handy for getting the best shot at restoring the threads while minimizing the material removed. I recommend running completely through the good thread and chasing the buggered one from the inside out.

I used this method for a buggered-up/cross threaded Luger grip screw hole. The tap thread was short enough to 'free-bore' once it cleared the 'good' threaded hole. I also used an old worn/dull 3/16"-30 tap as I wanted to push the metal back in place rather than cut it. Used oil, came out fine.
