Detailed Features

The threaded barrel (1/2x28) is included from the factory, so no barrel swap is needed to run a suppressor or compensator. Adjustable sights let shooters fine-tune for different distances, which matters in competitive settings. The aluminum frame keeps overall weight reasonable despite the 59 oz. loaded feel. The standard grip fits most hand sizes, and the lever safety is straightforward to operate. A lower Picatinny rail accepts lights or lasers without any modification.

Target Audience

The Defender suits shooters new to the 5.7x28mm platform, experienced handgunners looking for a high-capacity option, and anyone who wants a threaded barrel without paying for a separate upgrade.

Usage Scenarios
