What does the term "cylinder gap" refer to in firearms?

The term "cylinder gap" refers specifically to the space between the cylinder and the barrel in a revolver. This gap is crucial in the functioning of the firearm as it allows for the gas to escape when the gun is fired, preventing excessive pressure from building up in the cylinder. This escape of gases can help in the management of recoil and overall performance of the revolver. Additionally, the size of the cylinder gap can affect accuracy and velocity, with larger gaps potentially leading to a loss of velocity and decreased accuracy due to gas escaping before it can propel the bullet down the barrel.

Understanding the importance of the cylinder gap is vital for those involved in firearm maintenance and troubleshooting, as proper alignment and spacing are essential for safe and effective operation of the firearm.
