What would likely happen if a revolver's cylinder does not rotate properly?

If a revolver's cylinder does not rotate properly, it can lead to significant malfunctions that affect its operation. A malfunctioning cylinder may prevent the firing pin from aligning correctly with the cartridge in the chamber, resulting in a misfire. A misfire occurs when the primer of the cartridge does not ignite, which could happen if the chamber does not come into proper alignment with the barrel when the trigger is pulled.

Additionally, if the cylinder is completely stuck or fails to rotate due to mechanical issues, the revolver may not fire at all. Any issue with the rotation could obstruct access to the cartridges or potentially leave the weapon in an unsafe condition where it could not discharge properly.

Thus, both the possibility of misfires and the potential for the firearm to not fire at all illustrate a clear understanding of the consequences of a malfunctioning cylinder. The incorrect options fail to consider the serious issues posed by a cylinder that is not functioning correctly.
