Assuming 15 round mags, that’s 7 magazines with two already loaded, meaning 5 reloads. 2 seconds per reload is reasonable for someone moderately practiced and motivated. Fire 2-3 rounds per second, semi-auto with not much concern for accuracy in a fairly crowded area, takes 30-50 seconds for 100 rounds. 10 seconds for reloads, 50 seconds to fire, nothing special.

In NY, 15-round mags are illegal. I know this because I have to unload my 12-round mags if I return to NY after being on active duty.

Correction: 15-round mags made after 1994 are illegal in NY. Ones made prior are still entirely legal, and there is a healthy open market for them.

I know this because I studied the relevant laws in great detail throughout the history of NY's AWB, lived with that law for many years, and bought a number of such mags from stores that would have been long closed & owners jailed if doing so had not been clearly legal.
