Fire Extinguisher Recommendation

Considering adding a handheld fire extinguisher. My car already has the mount for it on the trans tunnel. Any recommendations on what/where to get one?

15.1 Fire Extinguisher
All cars without a fire system shall have at least a fire extinguisher securely mounted inside within driver’s reach
while normally seated, belts fastened and steering wheel in place. The bracket shall be metal and of the quick
release type. The mounting hardware shall be bolted through. Fire extinguisher bottles made of plastic or aerosoltype cans are prohibited.
The following chemicals are allowed:
Halon 1301, 1211, or Halotron I, hexafluoropropane, HFC-236a, CC0610, FE-36, two (2) pounds minimum; ABC
dry chem., two (2) pound minimum; 10BC potassium bicarbonate (Purple K) or sodium bicarbonate; or 1A10BC
multipurpose, ammonium phosphate and barium sulfate or Monnex. All fire bottles should have a gauge indicating
their charge status (which should be in the green range). Any bottle without a gauge should be weighed to
determine content. Once a bottle has been even slightly discharged it should be replaced or refilled.
