I've switched over to the M&P9/M&P9c for good. Sold my last glock a few months ago. I still have a few glock mags. I could leave them tucked away, but I have no use for them. It seems like it's a seller's market for regular cap mags. How much should I ask for, or should I just keep them? If I sell them, it would be to buy more M&P mags with the money. The mags are all 40 cal Glock factory mags. 1x22 rounds, 6x15 rounds (1 is .357 and 3 are marked LEO), 2x13 rounds.
