This is the only pistol from Sig I've been interested in, for a while. So... disappointing.
Are you referring to "Sig Talk"? I read about the guide rod/screw issues. Also saw someone complaining about the gun not going back into battery when he didn't rack it forcefully.
On the sample I handled, the slide would indeed hang-up just out of battery. Sales guy said it's because "the fit was tight." Apparently. But I dunno--I question whether or not it was that tight "on purpose."
I've long felt that Sig USA is no longer producing their guns to professional/military standards. I thought this might be an exception. But... if they can get the issues worked out and I read some favorable reports of long term reliability... I'd still be tempted.
