So I was looking through an old issue of Guns and Ammo Handguns (Dec06/Jan07 page 32) and I found this picture of a small automatic. It appears to be polymer, and it says Smith and Wesson on the left side and near the mag floorplate is the S&W logo. No idea what caliber, I can't make out what it says in the ejection port area. here's the pic, any guesses?
Crappy Sigma 380 - S&W redid the larger Sigmas - but this little 380 was sad. It was a zinc slide, if I remember correctly. And, there was a very small round count lifetime to this gun. Almost a disposable gun.
