Zeta6 SnapSafe Dry Fire Disk Review [2024]

Zeta6 SnapSafe Dry Fire Disk

During SHOT Show 2024 I covered the Zeta6 SnapSafe Dry Fire Disk. While we haven't covered Zeta6 before, I've been aware of their products for several years, and have been meaning to give them a try. After speaking with the owner and fiddling with examples at their SHOT booth, the owner gave me some samples to take home and try for myself. After several months of use, here are my thoughts on the Zeta6 SnapSafe.

Design of the Zeta6 SnapSafe

The Zeta6 SnapSafe is a pretty straightforward product. Think of the back end of a snap cap--now connect each case head, then make the whole thing out of soft rubber. Let's let Zeta6 explain in their own words:

SafeSnap mitigates long term damage to your revolver by absorbing much of this energy in two ways: The center plastic plug (inertia plug) absorbs some of the energy and individual diaphragm springs absorb even more. Together, these two features lessen the impact of the revolver’s hammer on the frame. And when installed, the bright yellow disc also serves as an empty revolver flag indicating that your revolver is empty and safe to store or to train with.

Most revolver manufacturers state that their revolver can be safely dry fired (clicking the gun while empty). But the reality is that impacting steel on steel or steel on aluminum is not good for your revolver. SafeSnap absorbs kinetic energy from the hammer through the firing pin to help protect your revolver. Highly visible bright yellow color indicates that the revolver is empty and safe to train with.

Firing pin energy is mitigated by molded inertia plugs and diaphragm springs located in each cylinder. SafeSnap training disc serves both as an empty revolver flag and a dryfire training tool. SafeSnap is simpler and safer than snap caps

In short, you insert the SnapSafe into the empty cylinder of your revolver, close the action, and go from there. This product works in place of snap caps for safe dry practice, all in one convenient package. Additionally, you can see the bright edges of the disk, helping you to visually confirm the status of your gun when taking them out of storage, practicing, or other situations.


Currently the SafeSnap is only available in .38 Special and .357 Magnum chamberings. There are three models, two five-shot variants supporting the Ruger LCR and S&W J-Frame, and a six-shot S&W K-Frame version. Each purchase comes with two disks of the same design, with bright yellow being the only available color currently. Zeta6 advertises a lifespan of 5,000 trigger presses before replacement, though I have not quite hit that number for verification.

Real World Use of the Zeta6 SnapSafe

I've used the Zeta6 SnapSafe quite a bit over the past several months, totaling up hundreds, if not over a thousand dry presses. So far, there are no signs of excess wear or damage, and any fouling is easily wiped away.

Unfortunately, fitment is not universal. The SnapSafe will not fit guns with recessed chambers, such as my S&W 66-1. Additionally, there is a limit to their elasticity. I have tried, and these will not fit the Colt Python, Cobra, or King Cobra, nor the S&W L-Frame or Ruger GP-100. I would love to see a rimfire variant to make for safer dry practice with those guns. Additionally, I think a S&W L-Frame and Ruger GP-100 variant would be a logical next step due to their popularity as well.

Instructor Considerations

As an instructor, I can see some serious benefits of the SnapSafe. Often times we use dry practice to help work fundamentals without noise or recoil. Throwing one of these disks into the cylinder can help protect people's guns while also providing a quick visual reference of an unloaded revolver for everyone.

Having a few spares in your range bag wouldn't be a bad idea. It'd be even better with some additional SKUs to cover other common revolvers.

Final Thoughts on the Zeta6 SnapSafe

Overall I really like the Zeta6 SnapSafe. They give me a little piece of mind when dry practicing with older guns, while being less cumbersome than snap caps. The high visibility nature of the design also makes it easier for me to check the condition of other's guns on and off the range. Their low price and durability don't hurt things either. If you're looking for something to safeguard your guns or add an additional layer of safety, be sure to check these out.

MSRP on the Zeta6 SnapSafe is $8.95. You can pick yours up >>HERE<<

Author's Note: Zeta6 provided me the SnapSafe as a product sample when visiting their booth during SHOT Show 2024. No mention of media coverage was mentioned by either party in exchange for product.
