Ring those barrels !

[Double Trouble]

The gunsmith did remove the extractors, but he still said they wouldn't ring true. He didn't see any loose ribs, nor any cracks in the barrels. In fact, he claimed that this was primarily a test for rib integrity - not cracks in the barrels.

Regardless - now I'm concerned...

One test I like to perform on a newly aquired set of barrels is to take a .001 piece of feeler stock cut it on a 45 degree angle and run it down the top and bottom rib looking for gaps.Barrel "ringing" will only tell the integrity of the barrel assembly not cracks.
