Kind of a long story. A million years ago (late 1980s) I served as a lieutenant in the NYPD’s Firearms and Tactics Section. Among my responsibilities was research and testing (it was a tough job, but someone had to do it). Anyway, SIG sent us a bunch of handguns to evaluate. As I recall there were some 230s (standard weight and airweight versions) and a couple of SIG 220s. All the SIGs performed flawlessly and we (I had several firearms instructors under my supervision) put many rounds through them. When it was time to send them back SIG didn’t really want them so offered them to us at a Very Good Price. So, I picked up one of the 220s (super reliable and darn accurate) plus an extra half dozen mags for it. My carry guns over the last +twenty years has been Glock semi-autos or an assortment of revolvers, so the SIG has been a safe queen except on rare occasions when I’d give her some exercise (I know she doesn't look it, but she's had around 1,000 rounds run thru her over the years). Anyway, this model has a fixed front sight, no rail (as is obvious from the photos) and is an older version of the design. Can anyone tell me which variant I own and where it falls among the SIG 220 line? Thanks! Oh, one last thing. Approximate value of the gun and all those magazines? Never bothered to unwrap four of the magazines.
