10-8 Performance

10-8 Performance is a specialized firearms training and equipment company founded by Hilton Yam, a veteran law enforcement officer and widely respected authority in the practical shooting and defensive firearms community. The company takes its name from the police radio code for “in service,” a fitting nod to its roots in professional law enforcement culture. 10-8 Performance occupies a unique niche: it sits at the intersection of high-end custom gunsmithing, firearms instruction, and product development, offering a range of precision-machined components, accessories, and training resources designed for serious shooters who demand the absolute best from their equipment.

The company’s product line focuses primarily on the 1911 platform and Glock handguns, offering aftermarket parts such as grip safeties, thumb safeties, mainspring housings, magazine wells, sights, and other components that meet the exacting standards of competitive shooters, law enforcement professionals, and dedicated enthusiasts. Each part is engineered to improve function, reliability, and ergonomics without sacrificing the durability required in real-world use.

What distinguishes 10-8 Performance from many aftermarket parts manufacturers is its emphasis on empirical testing and honest, unsparing evaluation. Hilton Yam’s background as a law enforcement firearms instructor informs every product decision—nothing is released unless it has been rigorously proven under demanding conditions. The company openly publishes its research and testing methodologies, earning a reputation for intellectual integrity that is rare in the industry.

Beyond hardware, 10-8 Performance has contributed substantially to the body of knowledge available to firearms professionals through articles, training materials, and community engagement. For law enforcement officers, military personnel, competitive shooters, and informed civilians seeking products that have been vetted by professionals whose lives have depended on reliable equipment, 10-8 Performance represents a gold standard of credibility and craftsmanship.
