Overview

Built for defensive and tactical applications, this 12-gauge semi-auto is configured with an 18.5-inch barrel, pistol grip, fixed stock, and ghost-ring sighting for fast target acquisition. It uses Benelli’s A.R.G.O. system, described here as a simple, self-cleaning, piston-driven action, and it accepts 2-3/4" and 3" chambers with a 5+1 magazine capacity. The black synthetic stock, anodized black receiver, and phosphate barrel give it a restrained, duty-oriented appearance. At 7.8 pounds with a 40-inch overall length, it is set up for users who want a compact shotgun for serious use while staying within the limits of its fixed configuration.

Pros

  • 12-gauge semi-auto platform with 2-3/4-inch and 3-inch chamber compatibility.

Considerations & Trade-offs

  • The fixed stock and pistol grip configuration may feel specialized, so it is less adaptable than a more adjustable setup for different users or shooting positions.
  • With an 18.5" barrel and 40" overall length, this is a compact tactical shotgun rather than a longer, more versatile field-oriented configuration.
  • The 5+1 magazine capacity is practical for defensive use, but it is still a limited onboard capacity compared with higher-capacity platforms.
  • This model is right-hand dominant, so left-handed users may find the handling and controls less natural.
