The Kel-Tec SUB-2000 Gen 3 is a popular pistol-caliber carbine known for its compact, foldable design and adaptability to various handgun magazines. This adaptability is facilitated by magazine well inserts designed to match specific pistol magazine types. For instance, a SUB-2000 configured for Glock 17 magazines will seamlessly accept them, while another variant might utilize Smith & Wesson M&P magazines. Choosing the correct insert is crucial for proper feeding and function.
This modular magazine system enhances the carbine’s versatility. Owners can leverage existing handgun magazine inventories, simplifying logistics and reducing costs. Furthermore, the variety of compatible magazines allows users to select ammunition capacity and type according to their specific needs, whether it’s target shooting, home defense, or other applications. The availability of extended magazines for certain calibers also expands tactical options.
