Considering the entrenched position at this point, belaboring solutions won't be fruitful, but alternatively, I'll pose this question...
As a bit of a gun hoarder, I think it's a very simple question to ask this: Even with Ruger's moderate decline in QC and CS in recent years, considering the same trend on a longer historical cycle at other companies, can anyone name a brand with LESS issues and BETTER service than Ruger in their same ballpark? The Italian SAA clones have issues as well, S&W seems to have a higher rate of failure even than Taurus these days... Sure you'll never have these issues with an FA 83, but you're talking about a semi-custom revolver that cost ~2-4x.
I'll also comment that I think there is a lot higher ratio of issues with "non-standard" models. The "Exclusives" seem to have a very high rate of issue, so I'm less surprised to hear this issue with a Convertible than a standard NV. Even though they're all cut on the same equipment, it sure seems like the 'limited models' have a lot higher rate of failure, so it makes me question what state Talo/Davidson's/Lipsey's buys the 'blanks' before they get assembled.
