Reducing the length of a firearm’s smoothbore tube alters its ballistic characteristics. This modification typically involves removing a portion of the barrel and recrowning the muzzle. For instance, a 28-inch barrel might be reduced to 18 inches. This process affects the shot pattern, muzzle velocity, and overall handling of the weapon.
Altering the length offers certain advantages, including improved maneuverability in close quarters and reduced overall weight. Historically, shorter barrels were favored for purposes such as coach defense and close-range hunting. However, such modifications are subject to legal restrictions in many jurisdictions, and improper execution can compromise safety and firearm performance.
