Threepersons Single Action Holster

In the early 1920s all levels of law enforcement were transitioning to automobiles, like the Ford Model T.  This was to keep up with the criminals and outlaws they chased. Holsters that worked fine on horseback were neither comfortable nor was it easy to acquire your pistol in the tight confines of an automobile seat. This sent career Peace Officer and Prohibition Agent, Tom Threepersons, on his redesign of the Threepersons Single Action Holster. Tom’s goal was to make it better for a fast draw and for wearing and accessing in an automobile.

He took his ideas to Sam Myers, an El Paso saddle maker.  Tom soon had a new holster made to his specifications. The holster became an instant success with his fellow El Paso officers. Within a few years Myers was advertising a “Threepersons, quick-draw holster” in their leather catalog.

Tom’s re-design of the belt holster cut around the trigger guard, exposing it completely, along with most of the top of the cylinder and all of the hammer. He tilted the holster backwards to put more of the butt of the pistol forward as well as placing it above the waist line while seated in an automobile.  This made the grip easy to grab quickly. The Threepersons holster design became the basis for the standard FBI holster, and indeed became known as the “FBI Tilt”

Correct Gun Belt Measurement

correct gunbelt measurement

Getting the correct gun belt measurement is easy if you follow some simple steps.

  1. Put on a pair of britches/pants you plan to wear with your gun belt
  2. Have handy any belt that currently fits you. You can even use a piece of string.
  3. Put the belt on and buckle it where you will wear your gun belt Slightly down over your hips in most cases. Remember the gun belt will be supporting another 4 pounds per pistol and holster {about 3 lbs for the pistol; 1 lb for the holster} That weight will drag the belt down. You may want to go another notch tighter in your measuring.
  4. Make note of the most comfortable hole in which the buckle goes through.
  5. Lay the belt on a flat surface and measure from the end of the buckle to the most comfortable hole. See picture below.
  6. Distance from the buckle end to the centre hole of your belt will be the measurement you supply us with. This is now your gun-belt size.
  7. Generally this measurement should be about 3 to 4 inches larger than your jean size.
