Rhett Neumayer is the founder, owner, and senior instructor of Demonstrated Concepts LLC. His work focuses on discreet armed defense, deep handgun concealment, close-range weapon access, and compact-firearm employment.
Professional Biography
Neumayer founded Demonstrated Concepts in 2012 to provide weapons-based defensive training to the public. His curriculum draws on experience in armed security, Brazilian Jiu-Jitsu, Sambo, weapons-based grappling, concealed-carry instruction, and human-tissue dissection. He reports maintaining his curriculum through continuing education with instructors including Craig Douglas, Ernest Langdon, Chris Cypert, Scott Jedlinski, and Chuck Haggard.
His best-known instructional contribution is Deep Carry, a method of positioning a concealed handgun with its grip at or below the waistband. The approach treats body shape, clothing, holster placement, firearm dimensions, concealment, and access technique as parts of one system. PHLster features Neumayer in its seven-part Imperceptible Handgun series, which teaches the method in detail.
Neumayer is also associated with the Cheek Pistol Concept, a method for stabilizing certain compact, stockless firearms by using the cheek as an additional index point. Independent firearms publications and evaluators have attributed the concept to him and explored its application across several platforms.
Across these subjects, Neumayer emphasizes practical testing over convention. His courses address the tradeoffs among concealment, access, control, and measurable performance, including circumstances in which conventional carry or shooting methods may not fit the user’s constraints.
P&S Connection
Neumayer has contributed to P&S discussions of instructor development and defensive-firearms training, including the Instructor Cheat Codes series. His work adds a specialized perspective on deep concealment, grappling-informed weapon access, and the evaluation of unconventional techniques.
