Modern gun

Modern guns are contemporary firearms designed with improved materials, ergonomics, safety features, and manufacturing compared with older firearms.

Common categories include:

• Modern pistols — compact firearms generally used for self-defense or military/police roles.
• Modern rifles — longer firearms designed primarily for accurate, controlled shooting.
• Shotguns — firearms that typically fire multiple pellets or a single projectile.
• Submachine guns — compact automatic firearms designed around pistol-caliber ammunition.
• Machine guns — automatic firearms designed for sustained fire.

Modern firearms may use polymers, advanced alloys, optics, electronic accessories, and improved recoil-control systems.
