Went to my local shop today in VT looking for a M&P9 2.0 with the 5” barrel and ran afoul of the new 15 round magazine law. Apparently this particular model only comes with a 17 round mag and I was told that the compact version’s 15 and 10 round mags aren’t compatible. So while they can sell me the gun there is no magazine that they say they can sell me for it. Any suggestion on how to get VT permitted mags for this pistol?
