Revolver Timing Check

Duration: 2:54

This video details how to check if a revolver is 'in time' or 'out of time,' a critical aspect of its mechanical function. It explains the roles of the hand and locking bolt in rotating and securing the cylinder. The demonstration covers single-action timing by slowly cocking the hammer and double-action timing by pulling the trigger, highlighting how the cylinder should lock precisely at the moment of firing. A malfunctioning Webley Mark IV is shown to illustrate the safety and accuracy issues caused by poor timing.

Quick Summary

Revolver timing is the cylinder's precise alignment with the barrel at the moment of firing. To check single-action timing, slowly cock the hammer; the cylinder should lock before full cock. For double-action, pull the trigger while supporting the hammer; the cylinder must lock instantly upon hammer release. Improper timing degrades accuracy and safety.

Frequently Asked Questions

What is revolver timing and why is it important?

Revolver timing refers to the cylinder's precise alignment with the barrel when the hammer falls. Proper timing is crucial for accuracy and safe firing, ensuring the bullet enters the barrel cleanly without obstruction or misalignment.

How do you check single-action timing on a revolver?

To check single-action timing, slowly cock the hammer. The cylinder should rotate and lock firmly into place just before the hammer reaches full cock. There should be no additional movement or 'click' when you manually check the cylinder after cocking.

How do you check double-action timing on a revolver?

For double-action timing, pull the trigger while supporting the hammer. The cylinder must stop rotating and lock into place the exact instant the hammer is released. Any delay or visible 'jump' indicates a timing issue.

What are the consequences of a revolver being 'out of time'?

A revolver that is 'out of time' can lead to significant accuracy degradation and potential safety hazards. The bullet may not align perfectly with the barrel, causing it to strike the forcing cone or frame, impacting performance and potentially causing damage.
