That's the standard magazine capacity for the .45 1911/1911A1.
Shouldn’t the 1911/1911A1 be declared the “official” gun of ,ew York? After all, it has the sanctified 7 round magazine. Surely the good governor will go out there and tell everyone that they should get a 1911 because it has a “good” number of bullets. Wouldn’t it be funny to promote the 1911 and enrage the gun banners that way. The 1911 being an iconic American weapon of war (boo, hiss). That would really upset the socialists.
So people who would have bought 9mm pistols are going to get .45 weapons instead, until somebody starts manufacturing 7-round mags for 9mm. Salse of 9mm are effectively banned in NY right now.
