I have three used in good condition Sig P226 20-round magazines, marked Sig and Made in USA. I would like to trade these for six Glock (genuine) G17 and/or G19 magazines. Third-gen magazines are fine with me. I'm in the Bellingham, WA area and can do face to face or through the mail. If you're interested in purchasing these magazines they would be $50 each plus $8 shipping for any or all. Magazines could use cleaning but lips and followers are in great shape. One has a slightly rougher, more phosphate-like finish.
