The United States Secret Service operates under one of the most demanding dual mandates in federal law enforcement: protecting the nation’s highest leaders and investigating financial and cyber crimes that threaten the country’s economic infrastructure. While the investigative side of the mission rarely requires firearms, the protective mission places agents and officers in situations where the right equipment can mean the difference between a successful day and a national crisis. Public interest in the weapons carried by the Secret Service spikes after high-profile security incidents, yet the agency deliberately keeps detailed inventories and configurations out of the open. What follows is a compilation of the firearms and less-lethal tools known through official procurement records, public observations, agency training references, and credible reporting as of mid-2026.
The Secret Service does not issue a single uniform loadout. Equipment is tailored by role. Plainclothes Special Agents working protective details prioritize concealability and reliability. Uniformed Division officers securing the White House complex and foreign missions carry a broader mix suited to fixed posts and patrol. Specialized units such as the Counter Assault Team (CAT), Emergency Response Team (ERT), and Counter Sniper (CS) teams operate with purpose-built long guns and optics designed for rapid response or precision engagement at distance.
The Sidearm Transition
For more than two decades the standard duty pistol was the SIG Sauer P229 chambered in .357 SIG. That cartridge delivered high velocity and was chosen in an era when many agencies sought greater terminal performance than the 9mm of the time could offer. By the late 2010s, however, ammunition technology had advanced. Modern 9mm defensive loads matched or exceeded the older .357 SIG performance in many ballistic tests while offering higher magazine capacity, lower recoil, reduced training costs, and greater commonality with other federal agencies and military units.
In 2019 the Secret Service began the switch to the Glock 19 Gen 5 MOS in 9mm. The Modular Optic System cut allows the addition of a red-dot sight when desired, though not every agent carries one as standard equipment. Observed configurations frequently include a Streamlight TLR-7A or comparable weapon-mounted light and upgraded night sights. Magazine capacity starts at 15 rounds, with +2 base pads sometimes fitted for additional capacity. The Glock 19 strikes a practical balance between size and shootability for agents who spend long hours in suits or business attire and must keep the pistol discreet yet immediately accessible.
Special Operations Division personnel, including members of the Counter Assault Team, often carry the Glock 47. This government-contract variant pairs a full-size slide with a compact frame and is typically equipped with a more powerful Surefire X300 Ultra light and an enclosed red-dot optic such as the Aimpoint ACRO P-2. The choice reflects the higher probability that tactical operators will face determined, possibly armored threats and will benefit from faster target acquisition under stress.
Shoulder Weapons and Support Firearms
Beyond the sidearm, Secret Service personnel train with and deploy several shoulder-fired weapons. The FN P90 personal defense weapon remains in the inventory. Its compact bullpup design and high-capacity magazine make it useful in close-quarters protective work and vehicle operations. The Heckler & Koch MP5 in 9mm continues to appear in training references and older inventory lists, although many peer agencies have largely moved away from submachine guns in favor of short-barreled rifles. The 12-gauge Remington 870 shotgun is still issued for situations that call for the distinctive terminal effects of shotgun ammunition or for breaching and less-lethal munitions.
The primary carbine for the Emergency Response Team and Counter Assault Team is the Knight’s Armament SR-16 CQB in 5.56×45mm NATO. These rifles are typically configured with short barrels (around 11.5 inches), suppressors such as the KAC QDC series, Aimpoint optics, and folding-stock adapters that improve handling inside vehicles and confined spaces. The SR-16 family has been publicly documented in use during major protective operations. In late 2025 the agency issued a Request for Information seeking a new 5.56 duty rifle that would remain operationally consistent with the existing SR-16 while meeting strict size, weight, suppressor, and durability requirements. The solicitation signaled continued modernization rather than an abrupt replacement of the current fleet.
Precision Firepower
Counter Sniper teams operate a different set of tools. Their primary long-range weapons are custom bolt-action rifles chambered in .300 Winchester Magnum, often referred to internally as “JARs” (Just Another Rifle). These are built on Remington 700 actions housed in Accuracy International chassis and fitted with high-end optics such as Schmidt & Bender scopes. The team also employs semi-automatic precision rifles, including the 7.62mm Mk 11 Mod 0 equipped with Trijicon ACOG or similar magnified optics. Counter Sniper operators work in pairs—one shooter, one spotter—and train extensively to neutralize long-range threats before they can endanger protectees. Public records note that until the July 2024 incident in Butler, Pennsylvania, the unit had rarely been called upon to fire in an operational setting.
Less-Lethal Tools
Not every confrontation requires lethal force. Special Agents, Special Officers, and Uniformed Division officers carry the ASP 16-inch expandable baton as a standard impact weapon. Uniformed Division personnel additionally carry oleoresin capsicum (pepper) spray and X20-series conducted-energy devices (Tasers). These tools provide intermediate options that allow officers to control subjects without immediately escalating to firearms, an important consideration when operating in dense urban environments or around large crowds of civilians and protectees.
Operational Context and Secrecy
The Secret Service’s equipment choices are driven by the unique nature of its protective mission. Agents must be ready to extract a protectee under fire, suppress an immediate threat, or hold a perimeter until local or federal reinforcements arrive. Weapons therefore emphasize reliability, controllability under stress, ammunition commonality where possible, and the ability to transition quickly between open outdoor venues and confined indoor or vehicle spaces. Suppressors on tactical rifles reduce signature and protect the hearing of agents and nearby civilians during high-intensity exchanges. Optics and lights improve performance in low-light conditions that often accompany evening events or indoor venues.
Because the agency’s primary duty is protection rather than routine street policing, it does not publish exhaustive equipment lists or photographs of every configuration. Most detailed knowledge enters the public domain through procurement solicitations on government contracting sites, after-action photographs from major incidents, testimony before congressional committees, and specialized reporting by firearms and national-security journalists. Even these sources leave gaps. Configurations can change with new contracts, lessons learned from incidents, or evolving threat assessments. What is known with reasonable confidence in 2026 is that the Glock 19 and Glock 47 form the backbone of the sidearm inventory, the SR-16 family remains the primary carbine for tactical response, specialized precision rifles support the Counter Sniper mission, and a mix of submachine guns, shotguns, and less-lethal tools rounds out the toolkit.
The 2025 Request for Information for a new 5.56 rifle and earlier interest in 6.5 Creedmoor designated-marksman rifles illustrate that the Secret Service continues to evaluate and update its long-gun inventory. Sidearm accessories, particularly the broader adoption of pistol-mounted optics, may also expand as training doctrine evolves and more agents become proficient with red-dot systems. Any future changes will almost certainly prioritize the same core requirements that have shaped the current arsenal: reliability under extreme stress, compatibility with protective operations, and the ability to support both close-quarters defense and longer-range precision when required.
In the end, the weapons carried by the Secret Service are tools in service of a singular objective—keeping protectees alive and the democratic process intact. The public sees only fragments of that equipment. The full picture remains, by design and necessity, largely out of view.
