The comparison between a revolver and a pistol depends on the context and intended use. Revolvers are generally simpler, more reliable, and easier to handle, making them ideal for self-defense and beginner shooters. They typically hold fewer rounds (usually 5-6) and are slower to reload. Pistols, on the other hand, usually have higher magazine capacities, faster reload times, and can be more accurate for experienced shooters. Ultimately, the choice between a revolver and a pistol depends on personal preference, specific needs, and circumstances.

A .357 revolver can potentially stop a bear, but it's not the ideal choice. While the .357 Magnum cartridge can deliver significant stopping power, larger bears, especially grizzlies and polar bears, may require more powerful ammunition, such as a .44 Magnum or larger caliber. Shot placement is crucial, and it's important to aim for vital areas like the brain or heart. However, bear encounters can be unpredictable, and it's generally recommended to carry a firearm specifically designed for bear defense when in bear country.

Police no longer use revolvers primarily due to advancements in firearm technology and the advantages offered by semi-automatic pistols. Semi-automatics typically have higher ammunition capacity, allowing for more rounds to be fired without reloading. They also have quicker reload times and better ergonomics, which enhance accuracy and ease of use in high-stress situations. Additionally, the trend towards adopting more modern firearms reflects the evolving needs of law enforcement for efficiency and firepower in the field.

In the movie "Revolver," the main characters reference the revolvers metaphorically rather than focusing on specific gun models. The film primarily examines themes of manipulation, power, and personal conflict rather than detailing specific firearms. The term "revolver" itself is symbolic, representing the cyclical nature of the protagonist's struggles. If you're looking for specific models or further details about guns in the film, they are not a central focus, and the narrative is more about psychological rather than physical confrontations.
