Description
If you run a Tokarev TX3, Titan, or Hammer shotgun, this magazine tube extension makes a practical upgrade that takes about as long to install as it does to explain. Just swap out your stock cap for this extension, and you're looking at two extra rounds ready to go. With 2 3/4" shells, you'll end up with a 6+1 setup, which means less time reloading and more time doing what you came out to do.
What Matters for This TX3 Extension
The extension bolts on without any permanent changes to your gun. That means if you ever need to swap it off, there's no holes drilled, no springs modified, nothing permanent. The steel and polymer construction holds up well, and the black anodized finish matches the factory look of your shotgun. Reviewers consistently mention how easy the installation is, and they note that the factory magazine spring handles the extra rounds without issue.
Real-World Use and Reliability
People have tested this extension in actual shooting scenarios, running everything from cheap birdshot to slugs. One reviewer documented over 250 rounds through the tube without a single malfunction. The extension even works well enough that it's been tested on some Redfield pump shotguns in addition to the Tokarev lineup. Field reports show it functions as it should, though one design note worth mentioning: if you field strip your gun, you'll need to remove the extension instead of just the stock cap, and you'll want to control that magazine spring so it doesn't launch across your workbench.
Why This Upgrade Makes Sense
Two extra rounds might not sound like much, but in any real shooting scenario, it cuts your reload cycle in half. Whether you're at the range, running a competition course, or doing anything else with your shotgun, this extension simply gives you more capability without compromising the gun's handling or adding bulk that doesn't fit. The fact that so few manufacturers offer these extensions for the TX3 platform makes this one of the only practical options available.

Frequently Asked Questions
Will this extension fit my specific TX3 model?
This extension is designed for the TX3, HDA1, Titan, and Hammer series 12 gauge shotguns. If you own one of those models, it will fit. Some users have reported it works on certain other pump shotguns like the Redfield Drive HD, though that's outside the standard compatibility list. If you're unsure about your exact model, check the Tokarev USA or SDS Imports website, or contact them directly to confirm before ordering.
Do I need a gunsmith to install this extension?
No. This extension is designed for tool-free installation and takes just seconds to swap out your stock magazine tube cap. You simply remove the cap, slide on the extension, and you're done. No drilling, no permanent changes to your shotgun, and no special tools required.
Will my shotgun's magazine spring still work with the extra rounds?
Yes. Real-world testing confirms that the original Tokarev magazine spring handles the extra two rounds without issues. You won't need to modify or replace the spring, and the extension works reliably with standard 2 3/4" shells right out of the box.
What if I want to remove the extension later?
You can remove it anytime without any permanent damage to your shotgun. Just swap your stock cap back on. The only thing to keep in mind is that when you field strip the gun for cleaning, you'll need to remove the extension instead of the standard cap, and be ready to manage the magazine spring during disassembly.
