I'm hoping p-f member zeleny chips in on this thread; he's one of the more knowledgeable P210 sources of accurate and objective information. I've had the pleasure of owning an "old school" SIG P210-6; it was a superb gun, but more something to appreciate and occasionally use than for contemporary carry or duty use.
Personally, I'd be highly skeptical of pretty much anything coming out of SIG these days; I've seen too many design and component issues-and too many shifts to lower-quality components during a model's production cycle.
The exception would be the Sigpro/P2022, who's quality seems to have been maintained unmarred, quite possibly due to established organizational contractual orders and their component/QC requirements.
Best, Jon
