12 Shot Rifle Cap Gun with Leather Scabbard

Use these steps to be sure that you get the best fit in a belt, radio strap, or suspenders.

Belts - Using a belt you currently wear, measure starting at the end of the belt (not including the buckle) to the hole you currently use. 

Radio Strap - Radio straps are typically worn under your gear but measure according to what you personally do. Using a piece of rope or string place it across your body over your shoulder from front to back. Bring the two ends together at your hip where you want the radio to attach at your hip. The top of the radio basket will sit here, holding the radio below. Measure the total length of that rope piece.

Suspenders - With your gear on, measure from the top shoulder seam of your shirt down your front to where the top of the suspenders would attach to your gear and repeat that process in the back, starting at the top shoulder seam down your back to where the suspenders would connect to the back of your gear.
