SDS Imports TX3 12EXT Features The SDS Imports TX3 12EXT magazine tube extension adds one additional round of 12 gauge capacity to the Tokarev TX3 series shotgun bringing total capacity to 5+1 with 2 inch shells. This extra round can matter in a defensive encounter giving the shooter one more shot before a reload is needed. The extension is engineered specifically for the TX3 HDA1 Titan and Hammer series shotguns so fitment is a direct match rather than a universal compromise. Steel and polymer construction keeps the extension durable while matching the factory finish of the host shotgun. Installation does not require permanent alterations to the shotgun so the extension can be added or removed without modifying the host firearm. This makes it a straightforward upgrade for shooters who want more rounds on tap for home defense or tactical use without committing to a different magazine tube setup. The finish is a black anodized steel and polymer combination that matches the TX3 s factory look. For TX3 owners who want more capacity without sacrificing reliability this extension is a simple purpose-built solution.
