Prior to moving to NY I lived in states that had no Rd restrictions in Mags, so I actually never knew about the law. I have a pistol that uses a 10 rd mag now, but want to get different one. Where can I find what gun can swap or use pre ban mags. Also what about online pistols that sell with say 12 or 15 rd mags? how can I find if they can use 10 rd mags and where can I get them if they can use them? Will the dealers swap 10 rd mags for the hi cap if I request it?
