Can a Ransom Rest be used to measure recoil? Analysis of 3,500 rounds of 38 Special, 9mm Luger, 38 Super, 40 S&W, and 45 ACP ammunition shows that it can, and that it is surprisingly sensitive to small differences in recoil.

The Ransom Rest is a machine designed to hold a handgun in the same position to test its mechanical accuracy. The gun is securely attached to the rocker arm, an appendage that attaches to the base. The rocker arm is free to move and pivots upward when the gun fires (Figure 1). The rocker arm “recoils as nearly like the human hand as possible” according to the manufacturer (www.ransomrest.com). Its movement is restricted by spring tension and steel and fiber friction discs.
