Frequently Asked Questions

Can I use 9mm ammo from my modern pistol in this revolver?

Yes. The Thunderball is chambered in 9mm Luger, the same cartridge used by most modern 9mm pistols. This means you can share ammunition between your handguns, which simplifies logistics if you shoot multiple firearms.

What's the difference between this and a traditional .45 Colt single-action revolver?

The Thunderball fires 9mm Luger instead of black-powder era calibers like .45 Colt or .44-40. If you want a classic single-action revolver that uses modern ammunition readily available at any gun counter, the 9mm chambering is the key difference.

Is this revolver suitable for Cowboy Action shooting?

The Thunderball is a genuine single-action revolver with the classic lines and handling you'd expect for that sport. Check your specific match rules, as some events may have caliber or configuration restrictions, but the design and function fit the category.

What does the case-colored frame mean?

Case coloring is a heat-treatment finish that produces the mottled, multi-colored appearance on the frame. It's both a traditional finish that gives the revolver its vintage character and a hardening process that strengthens the steel. It's not a coating that will wear off like paint—it's part of the metal itself.
