Because every box of ammo is slightly different, MTM has developed this pistol rest to take the mystery out of each box. The MTM pistol rest is so versatile that it will accommodate a Derringer to a 14″ Contender. The base locks into the fork at 20 different positions. Rubber padding is molded to the fork to protect your handgun. The rest was designed to be used without a sandbag, but they can be used with it. When not in use the fork has been designed to clip into the bottom of the base for compact storage. Made of tough polypropylene to last.
