WTT M&P Magazines my .40 for your 9 mm

[SandHill]

I would like to trade one or two M&P .40 10 round magazines, excellent condition, for one or two M&P 9mm magazines in similar condition. Have both full size and compact, can use both full size and compact. FTF preferred, San Francisco or Peninsula. Shipping OK if you have both full size and compact so we can each ship two for $6 flat rate.
