I am looking to purchase my first handgun and I have decided on the Springfield XD 4" 9MM with 15+1 Mag. I have been reading conflicting posts that say you can't buy handgun mags over 10 capacity. Now first of all is this true or is it now 20 max? Second does this affect what comes with the gun or only the additional you want to buy later? And the real question am I okay to purchase the gun in question. I am buying online and dont want to have any issues with legality. I am pretty sure I am okay as I have gotten some quotes on the same model at local stores so I wouldnt think they would quote me on a gun I cant buy. Thanks for the help in advance.
