GUN BELT, WESTERN BELT, and EXECUTIVE BELT: Measure, in inches, your EXISTING BELT from the end of the buckle to the hole that fits you the best. This measurement is your belt size. These Belts by Crossbreed have seven holes for proper sizing. The size you order will be made for use with the center hole. If you know that you prefer a belt with a longer tongue, add 1-2 inches to your measurement. If you prefer a fit with a shorter tongue, subtract 1-2 inches from your measurement. For most people, there is no need to change your belt size to allow for IWB carry of a single conceal carry pistol. INSTRUCTOR BELT: Please refer to the instructor belt page for the sizing chart and instructional video. CROSSOVER BELT: Please refer to the Crossover Belt page for the sizing chart, instructions, and videos. If you need assistance with belt options and sizing questions, kindly contact our customer service department at 888-732-5011. Please Note: DO NOT use your pants size as your belt measurement or order a desired size from buckle to tip. This will give you an incorrect fit.
