Have been a shooter for many years (mostly revolver) but have gone over to semi autos . My recent addition is a Model 59 which I enjoy shooting very much. I have a mag question. Located in New York State (not New York City) and have limited number of 10 round Mec-Gar mags. They work very well. A shooter from another state has offered me a couple of original S&W high capacity mags. On the baseplate they are marked 9MM S&W and have a Capital A on them also. Are these legal for me to have, carry with my Model 59 in New York State ? There is no identification as to whether they originated from the Model 59 or not. Anybody have any comments?
