I I have 5 brand new in package Smith & Wesson brand 8 round .40 S&W SW99 Compact magazines. They will also fit the Walther P99c. I understand they can be used for .357 Sig, but I will have to refer back to the package to be sure.
$130 shipped CONUS
I will update pictures later today, but they look like these. Granted the bag is a bit less worn on mine I think.
