Why is my gun's chamber stuck?

If the chamber is stuck its likely one of the following problems.

Friction Between Chamber & Frame

Using WD40 to lubricate the axle which the cylinder is resting on. Sometimes the cylinder will rub up against other parts of the gun if it isn't aligned properly, and spraying WD40 in these areas can make the gun work more smoothly and minimize any damage caused by friction.

Cylinder Not Rotating Correctly

Making sure that the cylinder doesn't have dirt, or anything that doesn't belong on the gun can be a quick fix. It's easy to get a small rock or dirt stuck in many different places of the gun. If a bullet doesn't leave the gun, but you hear it shoot the bullet, the bullet may be wedged somewhere in the gun causing an obstruction.
