I am a day late and a dollar short here. I have a SIG P239 but only have one magazine for it. Somehow, the spare mag was lost during my move back from Germany years ago. I have a nice nickel-plated P230 mag that I can offer as a partial trade if someone has a P239 magazine. The supply of P239 bags went South over the last couple of years and I was too slow to notice it happened! Added: Found out that a mag for the new P225A1 will also work in the P239.
