The Tailhook MOD 1 is the most compact pistol brace in the world. At less than an inch thick, it can be adapted to practically every platform on the market. To activate the brace functionality, depress the release button and pull the arm down. This creates the shelf that will counterbalance the muzzle weight of your large frame handgun. The ability of your forearm to hold the weight allows you to relax your shooting wrist and concentrate on trigger control. True one handed operation is achieved since you do not need a second hand to attach the brace to your arm. MOD 1 can be set up for right or left handed operation. We start with a solid piece of billet aluminum and meticulously machine every aspect for a part that is as nice to look at as it is to use. This version clamps to pistol buffer tubes or adapter spuds ranging from 1.17" to 1.2" in diameter. It features a limited rotation sling swivel QD socket as well. Weighing in at a scant 4.5 ounces, you will never feel it there. That is, until you want to use it. It is finished with a type III anodizing to withstand years of hard use.Remember that when this is installed on a pistol, it does not change the classification of the pistol with correct intended use. But recent ATF opinion states that using a pistol brace as shoulder stock could be considered manufacturing a rifle.
