Best way to fix it is to get the welder out, select a heavy rod, jack the power up to about 400 amps, lay the gun on the grounding table and run the rod down the barrel, across the the action, all the way to the end, and finally down across the trigger guard and magazine housing.
Sounds harsh, but it may save someone's life. I have seen several of the Braycos or Jennings pistols come apart. One incident, the slide was blown to the rear so hard that it sent peices of metal all over the shooter. He wasn't hurt bad, but was bleeding from several places on this face and shooting hand/arm. Had he not been wearing shooting glasses, he could have been blinded.
You always stand a chance of an accident with any gun, but these were made so poor the change of and accident/incident is very high. As a collector, I do own a couple of them, but their station in life is restricted to "wall hanger."
