I need to buy some 20 rounders and live in NY State. What are the decent mags to buy? What should be the most I pay for them and where are you folks getting them at? If there is no date stamp or LEO/Military Only stamp then I guess it could be considered pre-ban in the eyes of the man. No? Not looking for anything other than a reliable magazine, that is the only pre-requisite. Looking for options. Thanks.
