Be 18 or 21 depending on what you are buying, pass a criminal background check, have money, don't run afoul of the 20,000 plus firearms laws on the books.
No
Yes
It depends on the misdemeanor.
You will need the services of a lawyer.
Depends on what type of "gun" you are buying. Money, a clean police record and either 18 or 21 years of age are the start
Well a gun is 18, so I assume it must be 18 for bullets as well.
There is no apparent reason.
Federal law says 21 to buy a handgun and 18 to buy a long gun. Federal law says 21 to buy a handgun and 18 to buy a long gun. Unless Through Private sales,Gun shows and private transfer.Many states also allow minors to buy firearms.Although I have forgotten precisley which ones,I know Texas,Virginia,Nevada and Maybe Florida allow it. No point placing an age limit on firearms.
Not legally. Florida requires a permit to carry a gun on your person in public.
You simply need to be 18 or older, be able to pass an NICS background check, have valid identification, and be a resident of Florida or a state which a Florida gun shop can sell a firearm to.
IF the Pawnshop has a Federal Firearms License, and you are looking at a rifle or shotgun, and meet the other requirements to buy a gun (legal presence in the US, not a felon, not mentally incompetent, etc,) yes, you can buy a gun. You must be 21 to purchase a handgun. Depite the misinformation in the news media, pawnshop operators must follow the same Federal law as any gun dealer.
A bail bondsman cannot specifically carry a gun. However, they can carry a gun under Florida law as a normal citizen.
