Ten round mags are legal, but you can only put seven rounds in the magazine unless your at a gun range then you can load the mag with ten rounds..silliest bit of legislation .you are not allowed ten rounds for home or carry. They must have had a dart board. " ok let's see how many rounds,shoot the dart dummo I, mean cuomo"
PS: The 7 round limit goes into effect on April 15, 2013. So, 10 rounds are "less dangerous" between now and April 14th, but "more dangerous" between April 15th and eternity?
Glad I don't live in that crap eating state. I feel for those, who for one reason or another, have to.
