I am looking to purchase a single stack 1911 45ACP 10 round magazine. I have only seen them in 7 and 8 round so I am wondering if there is a problem in New York for having them. I do not need them foe any reason. My 45 is made for shooting 5 shots at a time for bulls eye shooting. But is would be fun to load to ten round magazines and just throw 400 grains of lead down the range as fast as I can pull the trigger. I am a calm person but that would be fun once in a while. I have seen them for sale but want to check the law first.
