I am having SO MUCH trouble finding mags for my M&P 9 and my M&P Shield, also 9 mm.
I live in CT, so now the mags I buy have to be lower capacity mags to satisfy the current CT ban. I can't find a damned 10 round magazine... anywhere. I've also been looking for an 8 rounder for my Shield since December and I've had no luck in that department, either.
Basically every gun store I've been to has given me a funny look and said "good luck" when searching for these products.
The closest I've come to a mag was when some idiot at a gun store tried to sell me a mag for an M&P 9C claiming it would work with my Shield.
