Frequently Asked Questions

What causes slow timing in a Smith & Wesson revolver?

Slow timing in an S&W revolver is typically caused by a worn or damaged 'hand'. This component is responsible for rotating the cylinder and ensuring it locks into place. When worn, it may not fully engage the cylinder's ratchet, leading to delayed lock-up.

How do you fix slow cylinder timing on an S&W revolver?

The most common fix involves replacing the worn hand with a factory oversized hand. This part is slightly wider, compensating for wear. It then requires careful fitting and honing with an India stone to ensure smooth operation and correct lock-up.

What is the function of the revolver hand?

The revolver hand, also known as the hand or pawl, is a crucial component in the firing mechanism. Its primary function is to engage the cylinder's ratchet teeth, rotating the cylinder to the next chamber when the trigger is pulled or the hammer is cocked.

Why is cylinder timing important for a revolver?

Proper cylinder timing is essential for safe and accurate revolver function. It ensures the cylinder is perfectly aligned with the barrel's bore when the hammer falls, allowing the bullet to pass through without obstruction, thus maintaining accuracy and preventing potential damage.
