How to repair slow timed Smith & Wesson revolver

B- 1:34

A slow timed revolver is one that fails to bring the chamber completely into alignment as the gun comes to battery. In this video Larry Potterfield, CEO and Founder of MidwayUSA, details how to fix the timing on a slow timed revolver. Typically, slow timing is caused by the hand not fully engaging the teeth of the ratchet on the rear of the cylinder. This problem is corrected by the installation of an oversized hand. Simply disassemble the revolver, install the new hand, and check the functioning of the action. If the action binds, it usually means the hand was too large. To properly fit the hand, remove it from the revolver and use a fine India stone to bevel its head. Not reinstall and check the timing. Repeat this process, checking your work frequently, until the fun functions properly.
