I can get aftermarket mags for all my M&P except the 22 Compact. I can also find OEM mags on ebay for all my M&P for $15 except the 22 Compact. I’ve found nothing but OEM and close to full price for this gun, oddly. Is there nothing else? i need several spare mags for this gun alone, much less all the rest so $30 - $35 a pop isn’t in the plans.
