What type of ammo does the M500 use?

The M500 shotgun is designed to use specific types of shotgun ammunition, and the correct answer refers to the commonly used rounds for this firearm. The M500 predominantly utilizes 2 3/4 inch "00" buckshot and 2 3/4 inch slugs, which are ideal for a variety of tactical applications, including law enforcement and self-defense scenarios.

"00" buckshot consists of larger pellets that can effectively incapacitate a target and covers a wide area, making it suitable for close-quarter engagements. Meanwhile, the 2 3/4 inch slug provides a single projectile option that is effective for accuracy at longer ranges when necessary. This versatility in ammunition type allows the M500 to be highly adaptable to user needs in various situations.

The other options presented do not align with the standard ammunition designed specifically for the M500. The 1-inch birdshot option is typically not used for tactical purposes, while 3-inch magnum slugs and 3 1/2 inch buckshot are not standard for this model, making the correct answer the most appropriate based on the capabilities and intended use of the M500 shotgun.
