I don't know a thing about this issue but I do know that certain Taurus models were discovered to have issues with being dropped after several years in the field. It was a Millennium model at the center of the controversy if that tells you anything. It was out before 2000 and it took at least 10 years for the problem to be discovered. I have one of those pistols and I have dropped it before with no problems. I keep it where it won't be dropped on anything hard now. It's too good of a pistol to let go.

I'm just saying that testing doesn't always reveal issues. It's possible the Sig was tested and not found to have issues until later. It happened with Taurus. Yes I know it's Taurus and not Sig but still. That pistol is a very good pistol. Start with 5000 rounds with no problems at all and accuracy that rivals the best Sig makes. And a Sig will cost about 3X as much for a similar pistol. I have a great Sig and I think the Taurus is great too in spite of the drop problems.
