Walk into any security staffing office in South Florida and you will hear these two letters constantly: D and G. If you are thinking about a career in private security, or you already work in the field and want to move into higher-paying armed positions, understanding the difference between a Class D and a Class G license is essential. It is also more straightforward than it sounds once someone actually walks you through it.

At Miami Guns, we work with a fair number of aspiring and current security officers who come in for firearms training and range time as part of their path toward a Class G license. Here is what you need to know about both credentials, what each one requires, and where a range fits into the process.

Class D: The Foundation of Security Work in Florida

The Class D Security Officer License is issued by the Florida Department of Agriculture and Consumer Services, Division of Licensing, under Chapter 493 of the Florida Statutes. It is the baseline credential required to work as a uniformed, unarmed security guard almost anywhere in the state, whether that is a retail store, a corporate office, a concert venue, or a residential community.

To qualify, applicants generally must be at least 18 years old, a U.S. citizen or legal resident with work authorization, and able to pass a fingerprint-based criminal background check. Before you can apply, you also need to complete 40 hours of state-approved training at a licensed security school. That training covers legal authority, emergency procedures, patrol techniques, and report writing, among other core topics.

Florida takes this requirement seriously. Working as an unlicensed security guard is treated as a criminal offense, and companies that knowingly hire unlicensed guards can face real legal exposure. So whether you are the one applying or the one hiring, the Class D license is not optional paperwork, it is the legal floor for the job.

Class G: Stepping Up to Armed Security Work

If Class D lets you work security, Class G lets you carry a firearm while doing it. The Class G Statewide Firearm License is an add-on credential, not a standalone one. You cannot apply for a Class G license unless you already hold an active, good-standing Class D license.

The bar is higher across the board. Where Class D applicants can qualify at 18, Class G applicants generally need to be at least 21. Beyond the standard background check, FDACS reviews Class G applications with extra scrutiny, particularly around any history involving violence or weapons charges, since this license authorizes carrying a firearm on the job.

The training requirement steps up significantly too. On top of your Class D coursework, Class G applicants must complete a firearms training course, commonly around 28 hours, covering firearm safety, handling, marksmanship, and the legal responsibilities that come with carrying while on duty. That course typically ends with a live-fire qualification, meaning you actually have to demonstrate you can safely and accurately handle a firearm under supervision before the license is issued.

Once you have the Class G license, the work is not finished. Florida requires armed guards to complete requalification training annually to keep the license active, even though the license itself is valid for two years. Skipping that requalification is one of the most common and avoidable ways an armed license ends up suspended.

Why Range Time Matters More Than People Expect

The firearms portion of Class G training is not something you can shortcut. Marksmanship, trigger control, and comfort under pressure all come from repetition, not a single test day. This is where a dedicated indoor range becomes valuable well before your qualification date.

At Miami Guns, our ten-lane, air-conditioned range in Hialeah gives security professionals a safe, low-pressure environment to build those fundamentals. Whether you are preparing for your initial Class G live-fire qualification or knocking out your annual requalification, showing up with real trigger time behind you makes a measurable difference. Staff are on hand to help you get comfortable with a firearm, and instructors are available if you want dedicated, one-on-one coaching before test day.

You also do not need to own a firearm to prepare. We rent handguns starting at twenty dollars and long guns at twenty-five, with a twenty-dollar hourly range fee that includes eye and ear protection. That makes it easy to log consistent practice sessions in the weeks leading up to your qualification without a major upfront investment.

The Miami Guns Takeaway

Class D is the entry point into Florida’s private security industry, and Class G is the step up for those who want to carry a firearm on the job. Both come with real training requirements and real legal weight, and neither one is something to rush through.

If you are working toward your Class G license or due for your annual requalification, stop by Miami Guns at 1040 E. 49th Street in Hialeah, call 305-688-8679, or visit miamigunsinc.com to get range-ready.
