Because it is a pistol, not a rifle.
1. Pistol 2. Rifle
A pistol CAN be held in one hand. A Rifle requires two hands.
First, it is rifle, not riffle. Second, no, or we would shoot tanks with a rifle. Cannon are more powerful. Finally, depends on the rifle. I have a .22 rifle and a .44 magnum pistol. The pistol is far more powerful than the rifle. I also have a .22 pistol, and a 30-06 rifle. The rifle is far more powerful than the pistol (in THAT example).

I'm not sure how the system of purchasing a pistol in Florida works, but converting a rifle into something which the BATFE would class as a pistol without being able to legally own a pistol would be illegal, not just in Florida, but in the entire US. Now bear in mind that, to be classed as a pistol, it would have to have just the pistol grip, and no buttstock. If it's a combination of pistol grip and buttstock, it's still considered a rifle, and is still legal, so long as the rifle is still compliant with state laws. Some states (New York, New Jersey, California, Connecticut, Cook County Illinois) still have so-called assault weapons bans in effect.

No, and if you want such a conversion, you need to build it up from a stripped receiver which was marked as a pistol on the Form 4473 when you bought it. If you buy a rifle, fill out paperwork showing that you're buying a rifle, then do such a conversion, you create what's considered a short-barreled rifle, which falls under NFA laws, and is illegal without first acquiring the appropriate NFA tax stamp.
You have to be at least 21 years old to legally purchase a pistol in the United States.
Yes, they are. Small Rifle can be used for Small Pistol, but not the other way around. Large Rifle can be used for Large Pistol, but not the other way around.
There are several firing ranges located in or near Manhattan. They include West Side Rifle and Pistol Range, Coyne Park Rifle and Pistol Range, Woodhaven Rifle and Pistol Range, and the Bay Ridge Rifle and Gun Range.
No you can not. Rifle rounds are longer than pistol rounds, which is part of the reason they are so accurate.
