It just makes me wonder if a pistol fires reliably for several hundred rounds...then has a FTE...then goes on to fire another few hundred rounds without fail, what would cause such a thing? If the extractor IS defective, wouldn't you expect it to fail to work more often? Or...could it be the odd wonky round gets in the mix?
The ammo being used in the Glocks is NOT the same ammo that was failing in the SIGs!! Same brand and type...OK. But the rounds that failed in the SIGs went into a bucket or were fired...so the ammo being used now in the Glocks is very likely from a different lot by now.
There is so much more to this story that we haven't been told...kind of makes me really wonder what the cases that failed to extract looked like. And all the cases that DID extract successfully...were they on the edge of not coming out? Could there have been magazine issues at play? I'm not sure on my 228 if it'll eject properly without a mag but nothing was said in the articles about this possibility.
For sure...the people from SIG who were assigned the task of trouble-shooting the problems didn't do a good job of it. Might have actually been something very simple to correct, but once you've changed a bunch of things trying to find the problem the customer no doubt has lost faith in you. Don't feel bad SIG!!
S&W ran into the exact same problem with NJSP back when they bought their guns. Extraction and ejection problems. Wonder why?
