Beretta 1301 shotguns are fast-cycling semi-autos commonly used for home defense, duty training, and practical shotgun matches like 3-Gun. Most owners are defensive shooters or competitors who want the platform to run flatter and handle faster under stress, especially on rapid strings and multi-target stages. Typical upgrade goals are better recoil and muzzle control, more consistent and comfortable gripping/shouldering when sweaty or armored, quicker and smoother reloads during loading drills, and a cleaner, more predictable sight picture—including when running an optic.
