From the outset, SureFire’s industry-leading innovation has been guided by the pursuit of cutting-edge solutions to high-stakes problems, and we’ve refused to compromise for more than 40 years. SureFire became the world leader in premium tactical gear for tier-one professionals by starting with laser technology. Less than 20 years after physicist Theodore Maiman invented the first working laser — described as “a solution seeking a problem”— Surefire founder Dr. John Matthews ignited a revolution in the firearms industry by inventing the first commercially available laser-sighted weapon in 1979. Since then, SureFire has continued to execute Dr. Matthews’ vision by constantly pushing the technological envelope in the areas of illumination tools, suppressors, hearing protection and more.
Decade after decade, we have met the needs of the most demanding users, driven by an unwavering commitment to our customers. SureFire currently serves the needs of everyone from the most elite professional military units and law enforcement professionals — who lay their lives on the line every day — to hard-core hunters, shooting sports enthusiasts and extreme outdoorsmen. They know they can depend on every SureFire product to lead the pack in performance, reliability and durability under the harshest conditions. They can’t live with second best, and neither can we. Our comprehensive lineup of illumination tools and tactical products — including our SOCOM-issue suppressors — is shaped both by our forward-thinking ideology as well as the experience of our distinguished past. If it bears the SureFire name, it is proudly designed and engineered with only the finest materials, then rigorously tested and precision-assembled in the U.S.A. Our proven success in this critical mission is made possible by a talented team of employees dedicated to supporting those who go into harm’s way. SureFire’s no-compromise approach has led to countless revolutionary products in our first 40 years, and we are building on this foundation to meet the unique challenges of the 21st century.
