SDS Imports TX3 Magazine Tube Extension Features The SDS Imports TX3 Magazine Tube Extension adds two rounds of additional 12 gauge capacity to compatible Tokarev shotguns using 2-3/4 inch shells. Built from steel and polymer the extension is designed to withstand the stress of repeated loading and firing without wearing prematurely. Installation takes only seconds and requires no permanent modification to the host firearm making it an easy upgrade for owners who want more rounds on tap without a gunsmith visit. The black finish matches factory Tokarev finishes keeping the extension visually consistent with the rest of the shotgun. Compatible with the TX3 HDA1 Titan and Hammer series 12 gauge shotguns this extension gives owners flexibility across the Tokarev shotgun lineup rather than being limited to a single model. For home defense or tactical applications where every additional round matters the extra capacity can make a meaningful difference without adding significant bulk to the firearm. The straightforward installation process means most owners can complete the upgrade themselves in a matter of minutes. For Tokarev shotgun owners looking to boost capacity quickly and affordably the SDS Imports TX3 Magazine Extension is a practical solution.
