Common Firearms Used in Armed Guard Services in Houston, TX

August 22, 2025 Category:

Armed security guards serve as a critical line of defense for businesses, properties, and events across Houston. Whether stationed at retail centers, industrial facilities, banks, or private estates, these professionals are trained, licensed, and equipped to respond to serious threats. One of the most important aspects of their role is firearm responsibility. Not only do guards need to know how to handle firearms safely and legally, but they also need to carry weapons that match the demands of their assignment.

Let’s explore the firearms commonly used in armed security guard services in Houston, TX, what’s required to carry them, and how these tools support the broader mission of professional protection.

Firearms and Security Licensing in Texas

In Texas, armed security guards are classified as Level III security officers. Unlike unarmed guards, who require only basic certification, Level III guards must complete additional classroom training, firearms handling instruction, and pass both written and practical exams. This training ensures they can carry and use firearms lawfully and responsibly while on duty.

The Texas Department of Public Safety oversees the licensing process. Once licensed, Level III guards are authorized to carry firearms while working, provided they follow all applicable regulations. However, this doesn’t give guards unrestricted authority. The weapon is used strictly for defense in accordance with the law and the scope of their duties.

What Armed Guards Do

While the presence of a firearm suggests a guard is ready for serious threats, the core responsibilities of an armed security guard go far beyond confrontation:

Deterrence and Prevention

An armed presence often deters criminal behavior before it starts. Whether it’s guarding a retail storefront or monitoring access to a warehouse, the sight of an armed professional signals that the property is protected.

Surveillance and Patrol

Armed guards routinely monitor premises through patrols and camera feeds. They look for irregular activity, assess potential vulnerabilities, and remain on alert during their shifts.

Emergency Response

In the event of a break-in, fire, medical emergency, or violent situation, armed guards are trained to respond immediately. Their role includes de-escalation, communication with law enforcement, and, only when necessary, using their firearm to neutralize a threat.

Policy Enforcement

In many cases, guards enforce business-specific policies, such as checking credentials, restricting unauthorized access, or securing sensitive areas. When enforcing rules, professionalism and communication are just as important as physical presence.

Most Common Firearms Used by Armed Security Guards

The firearm a security guard carries depends on employer policy, personal training, and state guidelines. Let’s look at the most common firearms used by security professionals in Houston today:

Glock 22

The Glock 22 is one of the most popular firearms among both law enforcement and private security personnel. Chambered in .40 S&W, it offers a powerful round with manageable recoil. Its lightweight polymer frame, high magazine capacity, and reputation for reliability make it a solid choice for guards who need a weapon that performs under pressure. 

Colt M1911

The Colt M1911 is a classic semi-automatic pistol originally developed for military use. Though over a century old, it remains a respected option in the security world due to its accuracy and stopping power. Typically chambered in .45 ACP, this pistol is often favored by guards who prefer a heavier round and a solid steel frame. 

Ruger LC9

Compact and easy to conceal, the Ruger LC9 is a lightweight 9mm pistol that appeals to guards working in close-quarters environments or performing plainclothes security. Its slim profile makes it easy to carry without drawing attention, and while it has a smaller magazine capacity, it’s valued for its portability and smooth action. 

Beretta Model 92

Known widely as the U.S. military’s standard-issue sidearm (M9) for decades, the Beretta Model 92 is a double/single-action pistol chambered in 9mm. It has an aluminum alloy frame and a steel slide, along with an open-top slide design that reduces the chance of jamming. With a standard 15-round magazine, this firearm is ideal for guards needing consistent performance, a high ammo capacity, and trusted handling in a variety of environments.

Heckler & Koch HK45

The HK45 is a modern, ergonomic semi-automatic pistol designed for .45 ACP rounds. Known for its ambidextrous controls and smooth trigger action, it’s used by many security guards and law enforcement professionals who want a high-performance firearm with stopping power. 

Safety and Responsibility

Firearms are tools, not solutions. A gun on a guard’s hip is only as effective as the person carrying it. That’s why training, safety, and discipline are the foundations of any armed guard’s career.

Guards must:

  • Complete their initial licensing and training through approved programs
  • Maintain their firearm in proper working condition
  • Practice situational awareness and de-escalation at all times
  • Only draw or use a weapon when absolutely necessary and justified by law

Improper use of a firearm can carry not only legal consequences but also put lives at risk. That’s why ongoing training and professional development are so important for any guard who is licensed to carry.

Common Questions About Firearms and Security Guards

Do Employers Provide Firearms?

It depends. Some Houston security companies provide standardized firearms and equipment to their armed staff. Others require guards to purchase and maintain their own firearm that meets company policy and state regulations.

Can a Guard Use Their Own Gun?

Yes, provided the weapon meets the company’s specifications. Most security firms will inspect and approve any personal firearm before allowing it to be used on the job.

Can Armed Guards Carry Off-Duty?

In many cases, yes. If the guard holds a valid License to Carry (LTC) in Texas, they may legally carry their firearm while off duty, provided they follow all applicable state and local laws. However, off-duty carry is not the same as being “on the job,” and any use of the firearm off duty is strictly subject to civilian laws, not employer policies.
